/* Supplement Streak website.
   Brand colours come only from aso-tokens.css (--brand, --brand-2, --brand-ink,
   --brand-soft, --on-brand). Everything below is neutral scaffolding.
   Motif: the square. The app's core view is a grid of one square per day, so the
   whole site is built from squares, rules and ledger rows instead of soft shapes. */
