/* ELN Studio — Bench mode.

 * One step in focus, controls big enough for a gloved thumb (56px), the same
 * calm navy as the rest of the notebook. State is said in words and shapes
 * (✓ ○ ◌ !), never by colour alone. Class names avoid the substrings the
 * app-colour theme layer repaints; tests/eln-plan-css.test.mjs keeps it so.
