Campaign VT slice 7 needs to transcribe VTank's own Vitals sliders
(minimum=0/maximum=100) and its long Profiles/Route named-item combos
control-for-control (docs/research/vtank-kb/08-ui-views.md §3's two
markup gaps). acdream's <slider> was hardwired to a 0.0-1.0 scalar and
<menu> always wrapped overflow into extra columns instead of VVS's
single scrolling column.
<slider min max>: optional literal attributes declaring the range the
bound value/onchange speak in (e.g. min="0" max="100" for a percent),
while UiScrollbar itself keeps its existing 0.0-1.0 internal math
untouched — MarkupDocument rescales at the binding boundary. Omitting
both (every pre-existing <slider>) keeps the exact historical identity
range.
<menu scroll="true">: wires UiMenu.Scrollable plus the same
track/thumb/up/down chrome sprites ConfigOptionsPageController and
VendorUiController already apply to their own Scrollable menus,
previously only reachable from C#. Omitting scroll keeps the
historical column-wrapping default.
Both are additive — no existing <slider>/<menu> markup changes
behavior. New pins in MarkupDocumentTests.cs shown to fail against the
prior MarkupDocument.cs (5 failures: Build_SliderWithNoMinMax_*,
Build_SliderWithMinMax_*, Slider_MinMax_Draws*,
Build_MenuWithScrollAttribute_*, Menu_Scroll_Draws*) before this
change, all green after.
