/* Closet Lab — from the "Home Lab Learning Journey" Claude Design project,
   which builds on Nocturne. Translated from the canvas prototype's inline
   styles into real classes.

   Fonts are SELF-HOSTED. Both the design and Nocturne itself pull Inter,
   Space Grotesk and IBM Plex Sans from fonts.googleapis.com; here they are
   served from this origin, so reading a page announces nothing to a third
   party and the strict CSP in _headers holds. Same reason the disc wiki
   self-hosts Inter. */
