/// <b>Why this table exists.</b> The DAT ActionMap singleton (empirically dumped
/// 2026-08-11, see <c>AcDream.Core.Input.RetailActionMap</c>'s class doc) carries 306
/// user-bindable rows. <see cref="InputAction"/> — the enum every OTHER acdream input
/// path (live dispatch, <c>KeyBindings</c>, <c>InputDispatcher</c>) already keys on —
/// has roughly half that many members, because it was authored around "what acdream
/// currently implements" (K.1a/K.1c), not "every action the 2013 client's keymap
/// screen can show." Two categories are the biggest gaps: 82 of the DAT's 87 Emote
/// rows have no acdream animation dispatch yet (only 5 are wired: Cry/Laugh/Cheer/
/// Wave/PointState — exactly the 5 that happen to carry retail default keys), and all
/// 48 CharacterSettings rows are hotkeys for the SAME <c>PlayerOption</c>/
/// <c>CharacterOptions</c> preference bits OP1's <c>CharacterOptionTable</c> and OP4's
/// Character-tab checkboxes already model — wiring "press this key, flip that same
/// server-synced bit" is a real feature (a hotkey-to-option-toggle dispatcher) that
/// does not exist yet anywhere in acdream and is out of scope for this slice (see the
/// OP8 register row).
/// </para>

/// <para>
/// <b>Every mapping below was verified two ways</b> before being added: (1) the DAT's
/// resolved English label/tooltip unambiguously names the SAME action as the
/// <see cref="InputAction"/> member's own XML doc, AND (2) where the retail default
/// key(s) for that DAT row are non-empty, they match
/// <see cref="KeyBindings.RetailDefaults"/>'s existing chord(s) for the candidate
/// <see cref="InputAction"/> (byte-verified 2026-08-11 against the installed dats —
/// see <c>RetailActionMapReaderTests.LiveDatTests</c> and this slice's
/// <c>RetailActionIdentityRoundTripTests</c>). A DAT row that could not be verified
/// BOTH ways is left OUT of this table on purpose — it renders on the Configure
/// Keyboard screen as a real, bindable, persisted row (see
/// <c>KeyboardConfigController</c>), it just does not yet reach any live acdream
/// consumer. Silently guessing a wrong mapping would misroute a user's rebind to the
