/* Set Sail — a calm coastal theme.
   Sea-glass accent, readable neutral surfaces, restrained nautical language,
   large touch targets, labels as well as colour, and motion that gets out of
   the way when the phone asks it to. */

/* --------------------------------------------------------------- tokens
   Each hue has three roles, because one value cannot do all three jobs:

     --x         the FILL. Bars, rings, indicators, chips. Never type.
     --on-x      the label drawn ON that fill.
     --x-text    the same hue as TYPE on a page background.

   The palette used to have only the fill. Using it as text put the most-read
   copy in the app at about 3.5:1, and the accent at 2.9:1. The hues below are
   unchanged; the text roles are new, and every pair is checked by
   test/contrast.test.js, which resolves color-mix() the same way a browser
   does and fails the build if any pair drops below its floor. */
