/* AiB Platform — the canvas map grammar (Морето днес on /free-tools/).
   Loaded only by free_tool_canvas.html, after css/public/public.css. The
   design is the owner-approved concept mockup, spoken in the platform's
   tokens: monochrome cartography on paper, the sea a quiet info-family
   wash, and the three semantic statuses (--ok/--warn/--danger) doing ALL
   the talking. Sodium never appears here — wordmark discipline.

   Ladder literals used: 1019 (the side panel becomes the bottom sheet —
   the 1020 two-column fold) and 719 (phone: the JS crops the open sea out
   of the viewBox; sizes bump to stay legible and tappable). */
