/* trackerui — the shared look for the *tracker apps.
 *
 * Extracted from gymtracker's web/static/app.css, which foodtracker had
 * already copied by hand ("Palette + type follow gymtracker's app.css").
 * That copy-paste is what this file replaces.
 *
 * Single fixed dark theme: violet accent on cool near-black. No light mode
 * and no toggle, matching what both apps already shipped.
 *
 * Depth comes from border + surface elevation, NOT shadows. The only shadows
 * in the original corpus were two button hovers; there is deliberately no
 * shadow scale here.
