/**
 * SEVA Admin SPA - layered on top of seva-modern.css + Bootstrap.
 *
 * Goals:
 *   - Modern, dense, professional layout (sidebar + main pane)
 *   - Brand-aligned with the public site (reuses seva-modern tokens)
 *   - No reliance on Bootstrap utilities for color/typography so we can
 *     also run with a strict CSP that forbids inline styles.
