Nine things a domain kept having to invent

Every change here started life as a workaround in a game and is really
the same finding: a fact about an entity had nowhere to live, so the
domain built machinery around the gap.

  Character.Label / Character.Voice — a tape is a character that speaks
  into the log, not a second spelling of Say. VoiceOf and CharacterLabel
  read them; Say obeys them.

  Game.Do — a real action queue, in order, so a widget can start an
  action. queueAction no longer drops what arrives while the runner is
  busy; it queues it.

  Widget.When + Gated + WidgetVisible — a widget declares when it is on
  screen. Nothing ticks, draws or blocks a click while its condition is
  false, so a HUD is hidden for a cutscene without a wrapper per widget.

  TopBar.NoteVar — the title was already discovered; the note beside it
  no longer needs a domain widget to push it in.

  Game.UseWithFail — the pair nobody authored is content, and belongs to
  the domain, exactly like ExitLook and ExitTake.

  Game.Player / Game.Walkboxes — a scene that names no cast and no floor
  means "the usual", instead of a defaults pass rewriting every scene.

  Game.WindowScale — Run's 4× is now a default, not a decision.

  SceneNav — the dev widget every game was writing.

  Colour text: DrawText paints in the colour it is handed, and GlyphW/H,
  TextWidth, WrapText and ClipText are the library's, not each game's.
