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).

id: screen-height
name: Screen.height
category: screen
kind: namespace-method
tokens: Screen.height
sig: Screen.height() -> int
tip: The framebuffer height in pixels.
order: 8
ns: Screen
member: height
---
Returns the height of the framebuffer in pixels — the number of drawable rows. Use it, together with <code>Screen.width</code>, to position elements relative to the bottom or vertical center of the screen instead of assuming a fixed size. A common use is keeping a moving object on screen by clamping its pixel row against this value. It takes no arguments and can be read during any handler.
```ludic
program GroundLine {
property Position { column: int = 0, row: int = 0 }
model Player { Position }
const TILE_SIZE: int = 16
handler SpawnPlayer phase Start {
spawn Player { Position { column: 3, row: 0 } }
}
handler DrawWorld phase Render {
Screen.clear(Color.MidnightBlue)
let ground_y = Screen.height() - TILE_SIZE
for (Position) in query [Position, {Player}] {
Screen.fill_rectangle(
x: Position.column * TILE_SIZE,
y: ground_y,
width: TILE_SIZE,
height: TILE_SIZE,
color: Color.LimeGreen)
}
Screen.show()
}
}
```
