/* Design v4 (2026-09-16) — obsidian glass + WebGL water-caustics background,
   ported from design/index.html per Dan: "it is a marketing gig that will
   make the site interesting till I attract enough geeks to use it." Applied
   everywhere (landing AND the full authenticated dashboard), not just the
   hero — the whole app now sits on the same dark glass surface with the
   caustics canvas behind it (see caustics.js, wired in via render.ts).
   Component structure (cards, tables, sidebar) kept as-is on purpose: this
   app has no templating layer, so every real page already shares these
   same classes — re-tokenizing them here reskins all ~15 pages at once
   without touching their markup. */
