/* ==========================================================================
   BatteryStatus - a thin layer over Bootstrap 5.

   House style: quiet, flat and dense.

   Near-white ground, white panels with a single hairline border and almost no
   shadow, small radii. Readings are set in a monospaced face with tabular
   figures so columns of numbers line up and a ticking digit does not shift the
   ones beside it.

   Colour is reserved for STATE. Green means healthy, amber means watch it, red
   means act - and nothing else in the interface borrows those hues for
   decoration. Every state is also spelled out in words and carries a shape
   (pill, dot, top-border), so colour is never the only channel.
   ========================================================================== */
