/*
 * WO-115b §2a — REVISED 2026-07-22: founder + CTO did not approve
 * theme-responsive; committing to the fixed premium identity instead (the
 * CTO's original recommendation). The site no longer follows the visitor's
 * OS light/dark preference — every visitor sees the same alternating
 * dark/light section rhythm on the homepage (§3's table), and a single
 * fixed light identity on the legal/contact/pricing pages and the nav/
 * footer chrome. Dashboard theme-responsiveness is unaffected — that's a
 * different app with a different rule.
 *
 * Carries forward the V1 mockup's visual language
 * (docs/design/marketing-mockup/index.html) — serif display type, mono
 * eyebrows, violet accent, ink/paper/surface/line tokens.
