Web app components

Every user-facing element type in the Qazana Strata language — themeable, framework-agnostic, token-driven. Syne is the signature face (brand + this title only); everything else is DM Sans, with system-mono for data and Font Awesome for icons.

Foundations

Brand/semantic tokens are overridden per app; neutral surfaces rarely change. Alpha tints use the channel form rgb(var(--primary-rgb) / .12) so one override re-tints everything.
