/* ============================================================================
   Basin & Range Home Systems — techno-futurist bento direction.

   The organising idea: the page is an instrument panel. Every region is a cell
   with a hard edge, and cell SIZE encodes importance — which is the one thing a
   row of equal cards cannot express. Nothing here is centred, nothing is a
   three-across feature grid, and the three bentos on the page deliberately run
   different rhythms so the layout does not repeat itself down the scroll.

   Dark is the direction, not a mode. A control surface that repaints itself
   white in daylight is not a control surface, so this page does not offer a
   light scheme — it declares `color-scheme: dark` honestly instead of shipping
   a light variant nobody designed.

   Numerals are set in JetBrains Mono throughout: prices, indices, step numbers,
   legend pins. Tabular figures are the whole reason a technical page reads as
   measured rather than marketed.
