/* Prahari command-and-control interface — Border Security command-centre theme.
 *
 * Designed for a room where someone is watching this for eight hours and must
 * not miss the one thing that matters. That drives every choice here:
 *
 *   - Dark tactical ground, because this is read at night next to live video.
 *   - Severity is carried by colour AND by a text label AND by position, never
 *     by colour alone. Operators are not all colour-normal and the room is not
 *     always well lit.
 *   - Almost no animation. Movement in peripheral vision reads as "something
 *     happened"; spending that signal on a spinner is wasteful, so it is spent
 *     only on genuinely new alerts.
 *   - Monospace for anything an operator may read aloud over a radio: camera
 *     ids, event ids, hashes, timestamps.
 *   - National tricolour used as identity, not decoration: a thin saffron/green
 *     signature on the brand, the classified strip and status states.
 *
 * No external fonts or CDNs, deliberately: a border outpost node has to render
 * its own interface with no internet, from a USB stick if necessary.
