/* ==========================================================================
   Fuel & Stint Calculator — endurance strategy tool.

   Scoped under .fuel (inside .racedata, so it inherits the race-data colour
   variables and type). It lives in the iracing/ folder because it belongs with
   the endurance content, but unlike its neighbours it reads NO data at all —
   there is no JSON, no refresh step and nothing is sent anywhere. It's pure
   arithmetic in the browser.

   Colour use
   ----------
   Three states carry meaning and each is ALWAYS spelled out in words as well:
   good (comfortable margin), warn (close to the edge) and bad (over the line).
   These are the race-data status colours, never the categorical ones, so they
   can't be confused with a series or a class.
