User-directed (2026-08-13): "we should only support modern resolutions.
Not any old format." New DisplayModeCatalog enumerates the window's
monitor (Silk IMonitor.GetAllVideoModes) once at GameWindow load and
curates via a pure, tested rule: modern widescreen families only
(16:9/16:10/21:9/32:9 within 2.5%), at least 1280 wide, must fit the
desktop (an impossible windowed pick is not offered - the measured
3840x2160-on-2560x1440 silent clamp class), desktop mode always
included, refresh-rate duplicates collapsed, ascending order.
The Config Resolution row consumes the catalog through two new optional
Bind parameters; its Defaults value becomes the desktop's own mode.
Fixture/headless callers keep the static preset ladder, which now drops
800x600 and is pinned by test to pass the same curation rule (the OP6 S4
"default must be re-selectable" invariant holds on both paths).
Deliberate retail deviation, register row IA-22: retail listed the
adapter's complete enumeration including 4:3 legacy modes and authored
800x600 as the Config default (gmConfigUI::InitOptions
SetDefaultValue(0x03200258); gmClient::Init @0x004047af). The catalog is
also the designated fullscreen mode-switch validation source for
#376/#388 - an offered mode is supported by construction.
Tests: DisplayModeCatalogTests (8 - filter/clamp/dedupe/sort/ultrawide/
desktop-inclusion/fallback-consistency); ConfigOptionsPageControllerTests
row-12 default updated. App suite 4,961/3 skips; UI.Abstractions 916.

Retail's world-camera FOV is not a constant: the applied vertical FOV is
m_fGameFOV / (viewportAspect - 0.1), recomputed on every aspect or
game-FOV change (CreatureMode smartbox sites 0x00452b2f/0x00453b14),
gated by Render::SetFOVRad's open (0, pi) acceptance (0x0054b2d0 -
rejected results keep the previous FOV). m_fGameFOV defaults to pi/2 =
90 degrees (0x00454649) and is what the Field of View option sets in
degrees (0x00451e6a; registered range [10,160] default 90 -
gmClient::InitUIPreferences @0x004035b0). Net effect: the horizontal
view stays ~85-90 degrees across aspect ratios; wide screens trim the
vertical slice instead of ballooning the sides.
acdream hardcoded FovY = pi/3 = 60 degrees on all four world cameras,
aspect-independent, and the Config slider wrote raw vertical-FOV
degrees. New: RetailFieldOfView (the law + gate, decomp-cited),
CameraController.GameFovRadians + SetGameFov + one ApplyProjection
chokepoint recomputing every camera on SetAspect/SetGameFov/
EnterChaseMode/RestoreState; ApplyFieldOfView now feeds the law;
DisplaySettings.Default.FieldOfView 60 -> 90 (the retail registered
default; the stored number changed MEANING with this commit).
The same seam closes a second latent bug the 2026-08-13 "squished" gate
report exposed: SetAspect only ever updated Orbit/Fly - the CHASE
cameras (the ones the player looks through) kept their creation-time
aspect across every mid-session resize, drawing the world at the old
shape stretched onto the new viewport.
The paperdoll camera stays outside the law by design (retail portrait
mode is UseSharpMode, not smartbox - DollCamera's own doc).
Tests: RetailFieldOfViewTests (golden law values at 4:3/16:9/21:9, the
constant-horizontal property, the rejection gate, controller propagation
incl. chase attach/restore + rejected-law aspect-still-propagates);
DisplaySettingsTests + RuntimeSettingsControllerTests updated to the new
semantics. App suite 4,953/3 skips; UI.Abstractions 916/0. AD-89 retired
in this commit; user settings.json migrated 60->90 by hand (stale
pre-port default).

Campaign OP slice OP9 code retirement (docs/plans/2026-08-10-options-panel-campaign.md
§OP9). The retail four-tab Options panel (OP1-OP8) is now acdream's one
in-client settings surface (D1) — this commit deletes the pre-retail-UI
surfaces it fully superseded. Pure retirement: no behavior change to
anything live, verified by dispositioning every one of the 15 src files
and 8 test files that referenced the deleted types before touching any
of them.
1. SettingsVM + SettingsPanel (the old F11 IPanel surface, unrendered
since Campaign V slice V11's ImGui deletion) deleted outright, plus
their two dedicated test files. IPanel/IPanelRenderer stay — ChatPanel/
DebugPanel/VitalsPanel still implement IPanel, so the contract does NOT
become unreferenced.
2. RuntimeSettingsController's SettingsVM binding seam deleted:
CreateViewModel, CreateViewModelBinding, RuntimeSettingsViewModelBinding,
the _viewModel field, UnbindViewModel, and every _viewModel? notification
call (ToggleFrameRate, LoadCharacterContext, RestoreDefaultCharacterContext,
SyncChatFromServerOptions). CreateViewModelBinding had zero production
callers (test-only). HasDraftPreview/DisplayPreview/AudioPreview stay on
IRuntimeSettingsPreviewSource (WorldRenderFrameBuilder and
SettingsParticleRangeSource still consume it) but now trivially mirror
the committed Display/Audio snapshot — HasDraftPreview was already
always false in production. GameWindowLifetime's matching
"settings view model" shutdown stage is deleted.
3. IDevToolsGameplayCommands + DevToolsGameplayCommands deleted from
GameplayInputCommandController.cs. All three members were dead:
ToggleSettingsPanel() had ZERO dispatch sites (ToggleOptionsPanel always
routed to _retained, never to _devTools); ToggleDebugPanel()/
FocusChatInput() had dispatch sites (F1/Ctrl+F1, Tab) but empty no-op
bodies (their ImGui DebugPanel/ChatPanel targets were already gone).
The two live dispatch sites are kept as inert `return true;` cases
(still consuming the key, matching the prior no-op's "handled"
contract) instead of falling through to a lower-priority scope.
SessionPlayerComposition.cs's `new DevToolsGameplayCommands()`
construction is removed. No `ToggleSettingsPanel` InputAction exists
(only `ToggleOptionsPanel`, rebound at OP3) — nothing to remove there
or from KeyBindings.RetailDefaults()/keymap fixtures.
4. GameplaySettings deleted entirely (the type, SettingsStore's
LoadGameplay/SaveGameplay/BuildGameplayObject, RuntimeSettingsController's
Gameplay property/SetAcceptLootPermits). Verified all 13 remaining
members (ToggleRun, AdvancedCombatUI, ShowTooltips,
VividTargetingIndicator, SideBySideVitals, CoordinatesOnRadar,
SpellDuration, AllowGive, ShowHelm, ShowCloak, LockUI, UseMouseTurning,
AcceptLootPermits — the three combat ones already died at OP4/AP-196)
were ALREADY bound through CharacterOptionTable/
CharacterOptionsPageController's server-bit seam at OP4 before deleting
the client-local mirror — no (c)-case genuinely-client-local member
was found; disposition (b) covers 100% of the surface. SetUiLocked
rewritten to compare only against the last value actually pushed to
_runtimeTargets (MUST-FIX 4's guard), with no second store left to
read or write. LiveSessionRuntimeFactory's SetAcceptLootPermits binding
now sends the wire option only (the GameplaySettings write-behind call
removed as dead output). CharacterSettings/DisplaySettings/
AudioSettings/ChatSettings and their SettingsStore Load/Save surfaces
are UNTOUCHED per the campaign contract.
Per-file disposition (15 src + 8 test files that referenced
GameplaySettings before this commit):
- GameplaySettings.cs, SettingsVM.cs, SettingsPanel.cs: the types
themselves — deleted.
- SettingsStore.cs, RuntimeSettingsController.cs,
LiveSessionRuntimeFactory.cs: real usage — API deleted/rewritten.
- RetailUiRuntime.cs, InteractionRetainedUiComposition.cs,
SessionPlayerComposition.cs, CombatUiController.cs,
LiveCombatAttackOperations.cs, LivePresentationComposition.cs,
FrameRootComposition.cs, RuntimeCharacterState.cs,
CombatCameraTargetSource.cs: doc-comment-only or interface-name
substring matches (ICombatGameplaySettingsSource) — left as accurate
historical record, no forward reference to the deleted type.
- Tests: RuntimeSettingsControllerTests.cs and SettingsStoreTests.cs
rewritten (Gameplay-specific tests deleted; SaveDisplay/SaveAudio/
SaveChat tests re-targeted off the now-public methods instead of the
retired SettingsVM draft/Save() indirection); GameplaySettingsTests.cs/
SettingsVMTests.cs/SettingsPanelTests.cs deleted; the remaining three
(CharacterOptionCombatSettingsSourceTests.cs,
CombatCameraTargetSourceTests.cs, LiveCombatAttackOperationsTests.cs)
were comment/interface-name-only, untouched.
5. Register: AP-196 (OP4's partial GameplaySettings retirement, which left
five fields as write-behind mirrors) is fully retired now that the
record is gone outright — marked ~~AP-196~~ RETIRED with its retirement
note, active-row count 143 -> 142. No other row cited the deleted types
directly (AP-194/AP-193 cite CharacterOptionTable.cs, not
GameplaySettings.cs).
6. Settings.json migration honesty: SettingsStore no longer reads or
writes the "gameplay" top-level key, so an existing file carrying one
from a pre-OP9 build is neither parsed nor dropped — the existing
SaveSection raw-JSON-text preservation mechanism (unknown top-level
keys survive every subsequent save) carries it forward untouched.
Two new targeted tests
(LeftoverGameplaySection_FromAnOlderSettingsJson_DoesNotBreakOtherLoads,
LeftoverGameplaySection_SurvivesAnUnrelatedSave) pin this.
InputAction.ToggleOptionsPanel's stale doc comment (still describing the
retired ImGui SettingsPanel) and a handful of other dangling doc
references (DisplaySettings.cs, ChatOpacityLink.cs,
SettingsDevToolsComposition.cs, InputDispatcherCaptureTests.cs) are
reworded to point at the current retail Options panel / OP8
KeyboardConfigController.
Build: dotnet build -c Release green, 0 errors. Tests: dotnet test -c
Release --no-build — 13,075 passed / 4 skipped / 0 failed (13,079 total),
down from the stated baseline of 13,155 passed / 4 skipped / 0 failed
(13,159 total) — the -80 delta is exactly the deleted SettingsVM/
SettingsPanel/GameplaySettings test surface (three whole files plus the
Gameplay-specific cases trimmed from RuntimeSettingsControllerTests.cs/
SettingsStoreTests.cs), with zero regressions elsewhere.

Fixes all three MUST-FIX findings from the OP6 REJECT review
(docs/research/2026-08-11-op6-review.md) plus its SHOULD-FIXes and NOTEs.
M1 — the "retail ships zero range captions" claim was a Binary Ninja
constant-folding artifact (the same class the header-string globals a few
lines above already worked around). The six SetSliderLabel call sites
byte-decode to reads of runtime-filled ID_Graphics_Value_* globals, not
immediate zeros (PE-byte-verified against the PDB-paired acclient.exe,
independently re-derived in this session, not just re-asserted from the
review). ConfigOptionsPageController.BuildSliderRow gained optional
rangeLowKey/rangeHighKey parameters wired for all six idx6 sliders (Camera
Stiffness Soft/Hard, Adjustment Speed Slow/Fast, FOV Narrow/Wide, Screen
Brightness Dark/Bright, Graphics Performance Speed/Detail, Degrade Distance
Close/Far) via the same SetRangeLabel mechanism OP5's Chat opacity sliders
already established. Mouse Look Sensitivity (idx3) correctly stays
uncaptioned — the one genuine SetSliderLabel omission. Class doc corrected;
gate-script lines 535/653-equivalent corrected in place.
M2 — the three Sound "Disabled" toggles were semantically inverted:
SoundManager::effect_sounds_enabled/ambient_sounds_enabled/
interface_sounds_enabled are all compiled = 1 in .data, and
UserPreferences::RegisterPreference binds the checkbox's boolean value
DIRECTLY onto those enabled-sense statics — checked-by-default means
enabled-by-default, not disabled. AudioSettings.SfxDisabled/AmbientDisabled/
InterfaceDisabled renamed to SfxEnabled/AmbientEnabled/InterfaceEnabled
(fresh JSON keys — the rejected slice's keys never shipped in an accepted
build); RuntimeSettingsStartupTargets.ApplyAudio now computes effective
volume through the extracted, independently-unit-tested pure function
ComputeEffectiveCategoryVolumes (enabled ? slider : 0f). This closes the
blast radius the review flagged: a missing key in an EXISTING settings.json
now falls back to AudioSettings.Default, which is enabled=true, so a fresh
launch is audible, not muted. AP-199's wording and gate-script step 6
corrected; the enshrined-inversion test rewritten to assert the correct
default and a new SettingsStore test pins the legacy-file fallback path.
M3 — UI_ChatFontFace now ships all five of retail's authored choices
(Arial, CourierNew, PalatinoLinotype, Tahoma, TimesNewRoman — a fixed
compile-time array at gmClient::InitUIPreferences, PE-byte-verified
present verbatim in .rdata, not a per-machine runtime enumeration as the
rejected slice's comment claimed). Default index 2 (PalatinoLinotype) now
indexes a real entry.
S1 — Bind() now emits the sixth trailing AddSeperator retail's own
InitOptions ends with (0x0049E80D), matching retail's 39-item ListBox (6
headers + 6 separators + 27 option-widget-rows) instead of 38.
S2 — Screen Brightness gets its own DisplaySettings.ScreenBrightness field
([-1,1], default 0) instead of overloading Gamma, which has a different
unit system (default 1.0, legacy [0.5,2.0] slider) and its own live
Settings-panel consumer.
S3 — UiScrollbar and UiMenu gained a settable TooltipText surfaced through
GetTooltipText (UiButton's existing pattern). Every slider and menu row's
own interactive widget (not just toggle/trio rows) now carries retail's
"<label>_Help" tooltip, verified as a universal suffix convention across
every AttachPreference site touched by this tab.
S4 — "800x600" added to DisplaySettings.AvailableResolutions: a genuine
retail display mode (Device::ForceDisplayResolution(1,0x320,0x258) at
startup) and the Config tab's own byte-verified Resolution row default, not
an invented preset. Defaults now lands on a highlighted, re-selectable
dropdown entry instead of an orphaned value.
S5 — four new/extended tests: ComputeEffectiveCategoryVolumes gets a
dedicated pure-function value assertion (Theory + a default-profile-is-
audible Fact) in RuntimeSettingsControllerTests, closing the "only event
order was asserted" gap that let M2 ship; a label/choice-key conformance
table in ConfigOptionsPageControllerTests enumerates every key this tab
queries (traced directly from the fixed code paths, not guessed) and fails
on an invented OR a dropped key; a per-row DefaultValue pin asserts every
row's default against the retail literal directly, independent of the
underlying settings-record defaults; and the S1 separator fix gets its own
39-item stacked-ListBox count pin.
NOTEs — AP-198's row count was always ten (its own enumeration never said
nine); the commit-message inconsistency N1 flagged is reconciled in both
the row and the section-summary line, and its Screen Brightness sub-clause
now matches S2. N2: Bind() now reads the scrollbar id from
UiTemplateListBox.ScrollbarElementId (dat property 0x72) instead of a
hardcoded constant. N3 (batch Defaults writes) and N4 (AfterApply on
Config-tab entry, needs no action) are left as recorded — out of this
rework's scope per the review's own disposition.
Full Release suite: 13,125 passed / 4 skipped / 0 failed (baseline
13,117/4/0 — net +8 tests added, 0 regressions, 0 removed).

Binds the retail Options panel's Config tab (LayoutDesc 0x21000029, 27
authored rows across 6 sections) through OP2's template mechanism and
OP3's per-page OptionPage model, matching the Character/Chat tab
controllers' established pattern.
The row table is transcribed directly from two decompiled sources —
gmConfigUI::InitOptions @0x0049E400 (row order, widget shape, defaults)
and gmClient::InitUIPreferences @0x004035b0 (the complete
UIPreferences::AttachPreference registration: every label/tooltip key,
every slider's real-unit range, every menu's enum choices) — which
resolves the research docs' own "U4" unverified slider-caption pairing:
retail ships ZERO range captions on this tab (every SetSliderLabel call
passes literal string id 0).
Consumer disposition: LIVE — Sound/Ambient volume-trio sliders and their
toggle halves (AudioSettings.SfxDisabled/AmbientDisabled now gate the
already-live engine write; RuntimeSettingsController.SaveAudio newly
pushes into OpenAlAudioEngine on every change, not just at startup),
Resolution/Full Screen (immediate window resize on save). NEXT-LAUNCH
(pre-existing precedent): Sync To Refresh, Field of View. STORE-ONLY
(register rows AP-198/199/200, TS-74 extended): Sound Features/Interface
trio/Play-Only-When-Active, the nine Graphics/Rendering-Quality rows
(Vulkan has no per-feature render knobs), Camera/Input's six rows and
Use Mouse Turning (no persistent mouse-turning camera mode), Chat Font
Face/Size (distinct new fields from the existing live ChatSettings.FontSize).
AudioSettings/DisplaySettings/CameraTurningSettings/ChatSettings each
gain new fields for their slice of the 27 rows, backed by SettingsStore
round-trips. A real bug caught by testing: the scrollbar scope lookup
used the standalone-layout root id (0x100001FF), which does not survive
base-merge into the host-mounted tree — fixed to scope from the tab
host's own page-slot id (0x10000213), matching Chat's established
pattern for the same shared-scrollbar-id hazard (0x10000201, authored by
both the Chat and Config ListBoxes).
30 new tests (27 authored rows register as 30 IOptionRow instances — the
three toggle+slider trios each register two). Full Release suite:
13,107 passed / 4 skipped / 0 failed (was 13,083/4/0 — net +24, the one
existing RuntimeSettingsControllerTests case updated for SaveAudio's new
live-apply call, not a regression).

Add QualityPreset enum + QualitySettings readonly record struct with
From(preset) table and WithEnvOverrides() env-var override layer.
Four presets (Low/Medium/High/Ultra) drive NearRadius, FarRadius,
MsaaSamples, AnisotropicLevel, AlphaToCoverage, MaxCompletionsPerFrame.
Env vars (ACDREAM_NEAR_RADIUS, ACDREAM_FAR_RADIUS, ACDREAM_MSAA_SAMPLES,
ACDREAM_ANISOTROPIC, ACDREAM_A2C, ACDREAM_MAX_COMPLETIONS_PER_FRAME)
override individual preset fields for dev spot-testing.
DisplaySettings gains a Quality: QualityPreset field (default High);
SettingsStore persists/loads it under display."quality" as an enum
name string with Enum.TryParse fallback. 12 new QualityPresetTests
cover the preset table (radii, msaa, aniso, a2c, completions) and all
six env-var override paths. 415 UI.Abstractions tests passing.
Wiring into GameWindow / WbDrawDispatcher / TerrainAtlas follows in
commit 2 of this task.

These changes were referenced by commits fc1e193 / 6273255 / 2818fcc /
df9f2fd in their messages but the actual edits sat uncommitted in the
working tree — caught by the pre-merge code review pass. Without this
commit the merge to main would lose all the panel-layout fixes the
user already live-verified.
What was orphaned:
· _window.FramebufferResize += OnFramebufferResize (Run() wiring)
· OnFramebufferResize handler — updates GL viewport + camera aspect
on window resize; force-resets panel layout via ResetPanelLayout.
· ResetPanelLayout(ImGuiCond) — positions Vitals / Chat / Debug /
Settings panels at sensible defaults relative to current window
size. Called at startup with FirstUseEver (imgui.ini wins on later
launches) and on FramebufferResize / View menu item with Always
(force reset).
· View → "Reset window layout" menu item.
· OnLoad seeding ResetPanelLayout(FirstUseEver) after panel
registration so first-launch users don't see all panels stacked
at (0,0).
· DisplaySettings.Default.Resolution: "1920x1080" → "1280x720" so
the default matches the WindowOptions startup size — opening
Display + Save without edits is a complete visual no-op (the
alternative would have triggered an immediate resize on every
first-time Save).
dotnet build green; tests unaffected.

Phase L.0 polish — the Display + Character tabs were persisting to disk
but didn't yet drive runtime behavior. This commit flips the live
switches.
DISPLAY ↔ GL window:
· FOV slider (degrees) → camera FovY (radians) on Orbit + Fly + Chase,
pushed every frame so dragging is visible immediately. Brainstorm
said FOV is a live-preview slider; this delivers it.
· VSync → _window.VSync, change-detected per-frame so flipping the
checkbox is instant. Applied at startup too so saved-VSync takes
effect before the first frame.
· Resolution → _window.Size on Save (TryParseResolution parses
"WIDTHxHEIGHT"). Live preview would be too jarring; resize is on
Save only.
· Fullscreen → _window.WindowState (Silk.NET borderless mode), also
on Save only.
· ShowFps → wraps the title-bar perf string. true → full perf line;
false → just "acdream" for a cleaner alt-tab. Default true matches
pre-L.0 behavior.
Defaults rebalanced — FieldOfView 75→60° (matches Orbit/Fly/Chase
FovY = π/3), VSync true→false (matches the previous WindowOptions),
ShowFps false→true (preserves the existing perf-in-title behavior).
Net effect: a user who never opens Display tab + later opens it +
Saves without touching anything sees ZERO visual change. Tests pinned
to the new defaults.
ApplyDisplayWindowState helper consolidates the window-side
mutations. Called from the SettingsVM construction site (apply
persisted at startup) and from the onSaveDisplay callback (apply
saved on demand). Malformed resolution strings are silently ignored
to avoid crashing mid-session if settings.json gets hand-edited.
CHARACTER ↔ active toon:
· _activeToonKey field replaces the hard-coded "default" — starts as
"default" (used for any pre-login Settings interaction), gets
swapped to the actual character.Name immediately after EnterWorld
in BeginLiveSessionAsync.
· onSaveCharacter callback closes over _activeToonKey by reference
(lambda captures `this`), so saves always write to the current
toon's slot without rebinding the lambda.
· After EnterWorld lands the chosen toon's name, the host loads
that toon's bag via SettingsStore.LoadCharacter and calls a new
SettingsVM.LoadCharacterContext to swap BOTH persisted snapshot
AND draft atomically — HasUnsavedChanges stays false on login so
the user doesn't see a "pending changes" indicator just because
they switched toons.
Per-toon storage already worked at the SettingsStore layer (commit
73749d1); this commit just plumbs the actual character name through
to the toonKey instead of always using "default".
2 new tests for LoadCharacterContext: atomic persisted+draft swap,
and pending edits getting wiped on swap (so pre-login bleed-through
can't write to the new toon's slot).
dotnet build green (0 warnings); dotnet test 1,309 / 1,309 green

Phase L.0 (cont.) — first concrete tab on the new Settings shell, in
the Easy-wins build order agreed in the brainstorm
(Display → Audio → Gameplay → Chat → Character).
DisplaySettings (immutable record): Resolution / Fullscreen / VSync /
FieldOfView (30-120°) / Gamma (0.5-2.0) / ShowFps. Six common 16:9
resolutions in the dropdown. Defaults: 1920×1080, windowed, vsync on,
75° FOV, gamma 1.0, FPS off — matches the brainstorm UX agreement.
SettingsStore: JSON persistence at %LOCALAPPDATA%\acdream\settings.json
(coexists with keybinds.json — own load/save path stays put, no
migration needed). LoadDisplay falls back per-field when keys are
missing (partial-file tolerant) and falls back to defaults when the
file is corrupt or the JSON is unparseable. SaveDisplay round-trips
preserved — unknown top-level keys (e.g. an `audio` section written
by a future client) are kept on save so older builds don't silently
drop newer-tab data.
SettingsVM gains a parallel display-state machine: persistedDisplay +
draftDisplay, SetDisplay mutator, HasUnsavedChanges checks both
keybinds and display deltas, Save/Cancel/ResetAll cover both
atomically from the user's POV (one Save commits everything, one
Cancel reverts everything). Constructor signature extends with two
new params; existing keybinds-only callers updated.
SettingsPanel.RenderDisplayTab replaces the L.0-shell placeholder —
Combo for resolution, Checkboxes for fullscreen/vsync/show-fps,
SliderFloat for FOV + gamma. Live-preview note in the panel body
matches the agreed UX: FOV + gamma update visibly while the user
drags; resolution / fullscreen / vsync apply on Save (live preview
would be too jarring).
GameWindow wires SettingsStore into the existing SettingsVM construct
site — load on startup, save on each tab Save. Errors print to
console and don't crash the panel.
19 new tests:
· DisplaySettings record (4) — defaults pinned, value equality, with-
expressions, AvailableResolutions sorted ascending
· SettingsStore (6) — round trip, missing-file → defaults, corrupt-
file → defaults, partial-file → per-field fallback, unknown-key
preservation, DefaultPath shape
· SettingsVM display (6) — initial draft tracks persisted, SetDisplay
marks dirty, Save invokes display callback, Cancel reverts,
ResetAllToDefaults covers display, Save-then-Cancel is no-op
· SettingsPanel display tab (3) — widgets render only when active,
resolution combo uses AvailableResolutions, no Combo emitted on
inactive tabs
dotnet build green (0 warnings); dotnet test 1,246 / 1,246 green
(243 Core.Net + 330 UI.Abstractions + 673 Core).
