/* app.css — Progent-branded dashboard + login styles for Vault Backup Manager.
 *
 * Colour palette derived from www.progent.com (extracted from production CSS):
 *   --pg-blue:       #011DC9  (primary deep royal blue — header, primary buttons)
 *   --pg-blue-dark:  #0015A0  (hover/pressed shade)
 *   --pg-blue-light: #456EA4  (steel blue — secondary accents, links)
 *   --pg-slate:      #4a4f62  (dark blue-gray — sub-headers, secondary buttons)
 *   --pg-gold:       #ffcc33  (Progent golden yellow — accent highlights)
 *
 * Health indicators use WCAG-AA-compliant dark green/red/amber on white.
 * No third-party CSS (D2/E2). Functions under CSP connect-src 'self'.
