docs(api): per-symbol pages, fuzzy search, deep token linking, hover cards
Rebuild the API Reference around one page per symbol and richer, verified content.

Pages & navigation
- One HTML page per symbol (kw-*, type-*, phase-*, screen-*, fn-*, annot-*, op-*)
  instead of a single scrolling page; namespace overview pages (ns-screen …
  ns-color) and a searchable index (api.html) with client-side fuzzy search.
- Sticky-header scroll offset (scroll-margin) so a jumped-to entry/param/color is
  never hidden, plus a flash highlight on the scrolled-to target.

Deep linking in every snippet & example
- Namespace members split: `Screen`→namespace page, `fill_rectangle`→method page;
  `Color`→palette page, `Charcoal`→its swatch — separately.
- Named arguments (`width:`) link to that parameter's anchor on the method page.
- Hover any token for a summary card built from the real API data (symbols.json).

Content & coverage
- Full authoritative surface documented from the compiler: every keyword, type,
  the 6 phases (Start/Input/FixedUpdate/Update/LateUpdate/Render, each its own
  page), all 22 annotations, namespace methods with parameter docs, builtins,
  the world_* reflection ABI, networking, operators — 155 symbols.
- Longer, clearer explanations; "model"/"model instance" terminology, not "entity";
  descriptive identifiers in every example (Position{column,row}, Velocity{delta_x,
  delta_y}, Health{current,maximum}, Player/Enemy) — no Pos/Seg/x/dx.
- Accuracy fixes from compiler ground-truth: world_count() takes no arg,
  world_query_next(property, cursor) arg order, event fields bind by name; dropped
  `when` and `module` (not in the self-hosted parser).

Tooling
- inventory.json + check.py: coverage guard (every symbol has a page), duplicate-
  token guard, and broken-link guard — fail CI so docs can't drift.
- validate.py: compiles every ```ludic example against bin/ludicc (158 compile).

kw-start start scenes keyword start scene Name start { … } Marks the one scene the game begins in. 50

start marks the scene the game begins in. Written right after the scene's name (scene Title start { … }), it tells the compiler which scene becomes active at boot: its on enter hook fires once, immediately after the Start phase, and its layers begin dispatching on the first frame. Mark exactly one scene start; if no scene is marked, the first one declared is used. Every other scene is reached later with become.

program StartSceneExample {
  scene MainMenu start {
    on enter { Screen.status("main menu") }
    layer Menu {
      handler ChooseOption phase Update {
        if Input.key() == 'p' { become Overworld }
      }
      handler DrawMenu phase Render {
        Screen.clear(Color.MidnightBlue)
        Screen.draw_text(x: 40, y: 90, text: "PRESS P TO PLAY", color: Color.White, scale: 1)
        Screen.show()
      }
    }
  }

  scene Overworld {
    layer World {
      handler DrawWorld phase Render {
        Screen.clear(Color.MidnightBlue)
        Screen.fill_rectangle(x: 100, y: 100, width: 16, height: 16, color: Color.Gold)
        Screen.show()
      }
    }
  }
}
