/*
 * First Digital theme layer over stock Bootstrap 5.3.
 * Palette from docs/FirstDigital-Brand-Guide-2025.pdf (p. 11):
 *   navy #003366, mid blue #307ab2, bright blue #38b2e3, red #cf333d (accents,
 *   use selectively), slate #2e404d (paragraph text), greys #8f9499 / #dedede / #f0f0f0.
 *
 * Everything here works by re-pointing Bootstrap's own CSS variables, so pages
 * keep using plain Bootstrap classes (btn-primary, text-danger, badge bg-success...)
 * and pick up the brand look automatically. Avoid hardcoded colors in templates.
