/*
 * KODENZO Support Tickets — customer-facing front end (2026-09-26).
 *
 * Deliberately does not redeclare any color/font token — every value here
 * reads from the CSS custom properties frontend.css already defines in
 * :root (--lf-navy, --lf-coral, --lf-text, --lf-text-muted, --lf-border,
 * --lf-radius, --lf-font-heading, --lf-font-body), and reuses frontend.css's
 * existing .lf-card/.lf-btn/.lf-badge/.lf-notice/.lf-empty-state components
 * directly rather than inventing parallel ones. The goal is a screen that
 * reads as part of the same KODENZO Hub portal as Dashboard/Licenses/
 * Account, not a bolted-on generic helpdesk.
