/**
 * Evolve — App-level styling on top of Bootstrap 5 + AdminLTE 4.
 *
 * Theme baseline (sidebar/topbar/primary color) is database-driven and injected
 * by themeHeadStyles() in includes/functions.php. This file only carries:
 *   - Design tokens (radius, shadow, brand accents) for use in markup.
 *   - Component refinements that are NOT covered by Bootstrap utilities.
 *   - Print rules.
 *
 * Avoid:
 *   - Hardcoded colors that duplicate --bs-primary or --evl-* (driven by /settings/theme).
 *   - !important (use higher specificity or a new class instead).
 *   - Dead overrides for elements that don't exist in markup.
