/* The landing shell: what every thing's page looks like. Measurements follow
   Vercel's Geist system (type scale, neutral ground, hairlines at 8% white),
   set in Geist itself, self-hosted. A site's style.css sets --accent (and
   --me, the local prompt) and nothing else. The accent is the page's
   identity: the primary button, the headline's second half, the shot's top
   edge, labels, icons and the status dot. Never body text. */
