   palori.co — SHARED TOKEN LAYER (run #3, mockup r3-B "studio")
   One stylesheet for every view: home, /plantuml, articles, hub,
   legal/docs, 404. Descends verbatim from the approved bake-off
   winner research/hero-mock-r3-b-studio.html — same token layer,
   same nav/footer, same proof device, same roster-card system,
   same article skin. Per-page files carry only page-local
   structure on top of this; nothing re-skins.
