/* Morse Code Translator. Functional layout before the design pass; existing tokens only.
   Unsupported characters and groups that aren't Morse are marked with an outline and a label, not
   color alone. The light is small and in --ink, never saturated red (spec §7, photosensitivity);
   off by default under prefers-reduced-motion (main.js). The boxes are 16px or more, so iOS doesn't
   zoom on focus, and three rows tall, so both fit at 360px with the keyboard open. */
