/*
  Detector Dynasty: shared styles for every page of detectordynasty.com.

  - Visual identity "Midnight & Brass": a midnight navy brand ground, signal gold
    accents, a parchment light theme and a navy charcoal dark theme. The values
    follow DetectorDynasty.App/Resources/Styles/Colors.xaml and ColorsDark.xaml
    (docs/design/2026-11-11-visual-identity.md).
  - The theme follows the visitor's device (prefers-color-scheme). The header,
    heroes, bands and footer stay midnight in both themes.
  - No web fonts, no third-party assets and no inline styles anywhere in the
    HTML: the Content-Security-Policy in /_headers allows styles from this
    origin only.
