Module map: `MODULES.md`; runtime model: `architecture.md`.

Self-contained module. Exports `ISLE_RENDERER = { Renderer, VIEW_W, VIEW_H }`.

- `new Renderer(canvas, { onEvent })` — pure draw: `draw(ctx, state)` renders
  whatever the physics state contains (blocks, enemies, birds, sling, HUD-ish
  scenery, popups). It never mutates `state`.
- VIEW_W/VIEW_H (1280x720) mirror physics constants VIEW — keep them in sync;
  the camera lives in state (set by physics/camera), render only applies it.
- S-3/S-5 (added): `drawBlock` rotates about the block COM when
  `bl.ang` is set (no-op at `ang=0`, so un-tipped blocks draw identically to
  the pre-S-3 output), and `drawBird` renders `landed` birds as live bodies
  alongside the `spent` corpses. The DOM-stub test only checks that drawing
  does not throw and that the sling band stops tracking a launched bird
  (bug #14 arm).
