CodeWhale Bot bd0fcfa7bf feat(web): Tideline deep-ocean refresh + new whale mark
Visual-language alignment with the Tideline TUI and the new brand asset:

- web/ palette re-grounded to the TUI WHALE_* tokens: deep-ocean dark is
  the default everywhere; the docs light sheet becomes an opt-in block
  carrying the LIGHT_* tokens (fixed two defects found by render inspection:
  the white mark vanishing on the light sheet and near-black button ink on
  cobalt).
- New brand mark integrated: traced SVG silhouette on the deep-blue tile
  (app/icon.svg), favicon.ico (16+32), apple-icon (180), web-app icons
  (192/512), new web app manifest, rebuilt OG card (mark + wordmark +
  identity phrase on the gradient, 1200x630).
- nav wordmark = new mark + name/tag; seal chips restyled; every
  bg-ink-as-dark idiom that would have inverted to ivory slabs fixed across
  components and pages.
- tailwind accents resolve through CSS vars so the docs light sheet
  re-themes; Fraunces/Noto Serif SC display loads dropped (Tideline
  typography: display = body family at heading weight).

Contract tests updated where product intent changed (blue-stage, docs-theme,
public-copy pins); the contracts themselves are preserved. No route, copy,
dictionary, or media-manifest changes.

Verified (integrator re-ran): check:facts OK; check:docs PASS; npm test
40 files / 341 tests all pass; npm run build clean (624 static pages incl.
the new asset routes); asset routes live-checked on the production server
(200s with correct content types). Render inspection at 390/768/1440 for
home + docs, mobile menu, focus ring, docs light toggle, install, models,
community, zh home, OG card — captures under /tmp/cw-captures/ (recorded in
the Ops ledger).

Refs #5573. No-Issue: Tideline program slice per the takeover plan.

/**
* <ThemeToggle> — a compact Auto / Light / Dark control for the date strip.
*
* The site ships the Tideline dark field everywhere; the toggle only renders
* on docs routes, where it switches the docs sheet between the dark default
* and the opt-in Blue Stage light sheet — the same preset pair the TUI
* offers. Showing it off the docs routes would be a control that appears to
* do nothing.
*
* "auto" removes the attribute and follows the site default (dark); "light"
* and "dark" force the choice via `data-theme` on <html>. The choice persists
* to localStorage and is re-applied before paint by the inline script in the
* locale layout, so there is no theme flash on reload.
