/*
 * FLARM Returns theme on top of Bulma 1.0.2.
 *
 * Bulma 1.x derives every colour shade from h/s/l CSS variables at runtime,
 * so overriding those here re-themes buttons, tags, links, notifications etc.
 * without a Sass build. Brand red from the logo: #DB001B.
 *
 * Design direction: an avionics-instrument feel, not a marketing site. The
 * palette shifts Bulma's neutral greys to a cool blue-ink cast (the colour of
 * cockpit displays), and brand red is reserved as a *signal* colour — the
 * live/current state — rather than a decorative accent sprinkled everywhere.
 * The one signature element is the status track (.track), which turns the
 * device's real repair lifecycle (Accepted -> Received -> Repaired ->
 * Completed) into the flight-path of the return. Everything else stays quiet.
 */

 * stack for speed and familiarity. */
