   misa.lol landing — base stylesheet
   Page-wide foundation every section builds on: design tokens, resets, the
   embedded display font, typography, layout primitives (.container/.section),
   and the components several sections share (.btn, .claim, .hint, .chip,
   .toast, .dag). Section files load after this one and may override it.
   Loads after navigation.css: never redeclare --nav-h here, navigation.css owns
   it (its media overrides would lose to a later unconditional declaration).
