/* DevPulse · brand guidelines
   A book of A4 landscape pages (297 x 210 mm). In the browser every page is a fixed-ratio box
   with container-type: inline-size and everything inside is sized in cqi, so the screen and
   the PDF are the same layout at a different scale. One family: JetBrains Mono, served from
   ./fonts so print never waits on the network. Artifact styles (posters, feeds, the night,
   merch) are copied from the ASCII v3 concept (in git history); the book frame comes last. */
