/* Bullseye Ballistics site. One stylesheet for every page.
 *
 * The look is the app's Field Instrument style (Bullseye-VC: ui/theme/Theme.kt): olive-charcoal
 * ground, signal-orange accent, chamfered panels, corner brackets, Rajdhani display type and IBM
 * Plex Mono labels. Colours are the app's own dark and light schemes. Dark is the default, as in
 * the app; light follows the system setting.
 *
 * Fonts are served from this site, not from Google Fonts, so a visit makes no third-party
 * request. Licences: assets/fonts/OFL-*.txt.
