/**
 * Generic-track admin styles (mockup3 — fdi-* namespace).
 *
 * Color scheme inherits the WP admin's primary accent via
 * `--wp-admin-theme-color` so the importer matches whichever admin
 * scheme the user picked (Blue / Light / Midnight / etc.). Buttons,
 * focus rings, tile selection state, progress bar fill and the step
 * indicator all derive from that single variable — no hardcoded
 * #2271b1 anywhere in this file. The legacy `style.css` at the
 * plugin root still loads but its selectors target `.theme-*` /
 * `.demo-contents-*` markup the new tree doesn't emit.
 *
 * Layout reference: docs/ux-research/mockup3.html.
