Cuts the main-chunk cost of the sky consumer (#47, merged). Branch carries dev 913a66eb (merged in; includes #47 and #45).

Entry chunk (vite build, index-*.js, gzip -9), measured twice:

build	raw	gzip
dev `a9a75fc6` (before #47)	3,731,592	944,178
dev `913a66eb` (#47 + #45 merged)	3,855,494	998,398 (+54.2 KB over `a9a75fc6`)
this PR	3,733,993	944,888 (+0.7 KB over `a9a75fc6`; -53.5 KB vs dev `913a66eb`)

The +0.7 KB over a9a75fc6 includes #45's title-bar code, so the sky-state part of this PR is under that. Baked tables are in the lazy terrainSky chunk (117,567 raw / 50,056 gz), loaded with the scenes; the entry has none.

Backdrop constants (skyBackdrop reads these; relative luminance, rounded outward to 6 places): Day 0.237309-0.928052, Dusk 0.016727-0.967912, Night 0.058099-0.077467, Auto 0.016727-0.967912. They come from terrainDrawn, which now finds the sun-glow peak and the darkest patch by compass search from the best coarse samples (3 degree grid, 0.5 degree horizon ring, zenith, 0.25 degree sun patch); the old 3 degree grid gave Day max 0.9192 and Dusk 0.9647. Contrast table: the 3 passing cells (night Light/Silver/Dark/Butter 4.78 / 4.69, Midnight text 5.05) did not move; day Noonday is 3.71 / 2.56 as before; every other cell is 1.00 or as before.

Drift test (skyForState.test.ts): the constants must bound the computed union, sit within 1e-5 of it, and bound an independent sweep (golden-angle spiral of 20,000 points plus a 0.05 degree grid around the sun) within 5e-4. Mutating the day top to the old value, the day bottom, the dusk top, and setting the refinement off each fail it. Scene suite 22 files / 364 tests pass; prettier and eslint clean on touched files.

Service-worker precache (Void's question): there is none. vite.config.js:105-113 runs VitePWA with strategies: 'injectManifest' and injectManifest: { injectionPoint: undefined }, so no manifest is injected, and src/sw.ts has no precache, no __WB_MANIFEST and no workbox import: it only proxies authenticated media (install, activate, message and fetch handlers). The built sw.js is 1,660 bytes on both dev 913a66eb and this PR, byte-identical, with no precache/workbox/asset references. So the lazy terrainSky, Scene and Terrain chunks are not precached by the service worker on either; total precache size is 0 on dev and on this PR; they load over the network (and the browser HTTP cache) when the scene starts. No SW config was changed.

Not measured: load time or first paint, brotli sizes, runtime caching by the browser or host (netlify.toml headers), the dev server, a deployed build, and anything in a browser. One build each; the dev builds used deps from npm ci on this lockfile.

scene: keep the terrain sky and baked tables out of the main chunk

skyBackdrop reads constants (the union of the ridge and terrain skies, rounded
outward) instead of computing it, and the door imports skyForState lazily with
the scenes. A test fails when the constants drift from the computed union.
Main entry chunk vs dev: +0.4 KB gzip, down from +51.5 KB.

scene: terrain backdrop range found by refinement, not a grid

terrainDrawn finds the sun glow peak and the darkest patch with a compass
search from the best coarse samples; constants regenerated (Day 0.237309-0.92805,
Dusk 0.016727-0.967912). The drift test sweeps its own grid (golden-angle spiral
plus a 0.05 degree patch around the sun).

scene: Day sky bound was 1.2e-6 low; refine to 1e-6 degrees and check both directions

Day lightest 0.92805 -> 0.928052 (true terrain peak 0.92805117...). The compass
refinement now halves to 5e-7 degrees; the drift test checks the constant against
the refined computation and an independent golden-section sweep, exact to
[extreme, extreme + 1e-6).
