 * The public pages (epic 4, T4.1; the second look, 2026-11-08, research/site-design.md: "Accent light"). The owner:
 * beautiful, interesting, high-tech, little animations, simple, no complex patterns, not heavy. So: white paper and
 * system fonts; the site's colour as the light of the page (a wash at the top, the glow of the two actions, the
 * rings); one dark console for the code; every motion is CSS, composited, finite, and stopped for a visitor who asks
 * for less. Phone first (mobile.md §1). The site's colour arrives as --accent, --on-accent (text on it) and
 * --accent-text (it as text on white), all three from layout.ts, and nowhere else: another look is one setting.
