 *

 * /c/ and /card all depend on, so the landing page keeps out of that namespace
 * entirely rather than risk collateral damage on pages nobody would think to
 * re-check.
 *
 * Tokens mirror the app's own (CLAUDE.md): #FAFAF9 ground, #FFFFFF cards,
 * #EEEEEC hairline borders, #1A1A1A / #6B6B6B text, Obsidian accent. Type is
 * Outfit 300 for headings, Hanken Grotesk for body, matching the app exactly.
 *
 * Layout is left-aligned and asymmetric rather than centred: one measure for
 * headings, a narrower one for prose, hairlines instead of boxes. Nothing
 * animates beyond a hover opacity.
