/* ============================================================================
   HOMEPAGE in the lamp look (index.html with no chart open). Loaded after
   styles.css and lamp.css, and scoped to html.lamp like lamp.css, which app.js
   removes as soon as a chart opens, so nothing here can reach an engine.
   The gallery's own rules (styles.css, LANDING / GALLERY) still lay out the
   rows, cards and pagers; this re-points their colour and type tokens at the
   lamp palette and overrides what was drawn for a dark-only page (glows,
   grain, centred header). Spec: docs/superpowers/specs/2026-10-19-one-site-look-design.md
