/* FlossyPurse Studios — the shared shell.

   The design tokens and the app shell (rail, top bar, tab bar, search
   palette, footer) plus the few pieces every page leans on: the eyebrow,
   buttons and cards. Every studio page links this BEFORE styles.css, and the
   Data app (a separate app served at /data on this domain) links it too, so
   the two look like one site. Class names here are a contract with Data:
   rename one and Data breaks. Page styles stay in styles.css. */
