/*
 * tabletrac.css — TableTrac visual language for the dashboard.
 *
 * Token-driven styling with a single set of CSS custom properties that
 * cascade through every component. Linked from layouts/header.php so it
 * applies to every authenticated page; per-page templates override only
 * truly local layout deltas.
 *
 * Palette source: TableTrac brand style guide.
 *   Minsk (#3C286B)            — primary plum brand color
 *   Dark Indigo (#1C1747)      — body text + dark mode bg
 *   Pale Steel Blue (#8FA6D5)  — accent / links / focus rings
 *   Blizzard Blue (#93D6E1)    — info tints
 *   Emerald (#43BA81)          — success state ONLY
 *   Mustard (#F4D157)          — warning state
 *   Tangerine (#F68D39)        — escalated warning
 *   Cinnabar (#F0493A)         — error / destructive
 *
 * Naming: --tt-* for tokens, .tt-* for utility classes. Existing dashboard
 * classes (.header, .sidebar, .content-area, etc.) are also styled here so
 * the existing PHP markup picks up the new look without HTML changes.
