/* Live Oak outbound — the operator's console.
 *
 * Design language: a sibling of Live Oak's inventory manager (../inventory_manager/
 * frontend/src/index.css), so the two tools feel like one company's software. A dark
 * navy sidebar (#0b1120) carries the brand and the five views; the working surface is a
 * cool light grey (#f4f5f7) with white cards, soft shadows and radii of 6/10/14px.
 * Plus Jakarta Sans for everything, JetBrains Mono for figures (arm keys, counts,
 * rates). Tables follow the inventory manager's DataTable: sticky header, small
 * uppercase column labels, quiet row hover. Status words are pill badges; buttons are
 * primary (blue, the default `<button>`), `.secondary` (white) and `.danger` (red).
 *
 * The one loud element is still the state bar at the top of the working area. Its
 * colour answers "is anything going out?": green SENDING, amber NOT LIVE, solid red
 * when the kill switch is on (with hazard stripes) or a protective action has failed.
 * It is safety-relevant — do not make it quieter than the rest of the page.
 *
 * There is no inline CSS anywhere in the templates, because the Content-Security
 * Policy is `style-src 'self'`. Adding a `style="…"` attribute will silently do
 * nothing; add a class here instead. Fonts are self-hosted in /static/fonts
 * (`font-src 'self'`) and icons are CSS masks over /static/icons/*.svg — see
 * dashboard/static/README.md for why they are not inline <svg>.
