 * One accent, two tokens: --accent is the colour itself (fills, dots, borders);
 * --accent-ink is a version dark enough to carry words on the light theme. In dark
 * mode the raw accent reads fine and -ink collapses onto it.
 * Filename carries the version: bump it (style-2.css) on every visible change,
 * because a ?v= query does not bust the edge cache.
