/* ═══════════════════════════════════════════════════════════════════════
   LANDING — editorial print aesthetic
   Ported near-verbatim from the app's vetted look (src/styles/landing.css,
   Kyle-approved). Adapted for the standalone marketing site:
   - hardcoded theme colors tokenized so dark mode works via OS preference
     AND the site's theme toggle (one [data-theme] resolver, no app shell)
   - beta-capture form styling added (pre-launch CTA; no buy buttons)
   - persona footer links added so /for/* pages are discoverable
   Fonts, spacing, and type scale are unchanged from the vetted design.
   Min font size here is 12px (labels); nothing smaller. No emojis.
