/* =============================================================================
   Sawaf Services — "Fire Danger"

   The conceit: the roadside fire danger rating sign every person in British
   Columbia has driven past ten thousand times, pointed at office technology
   instead of forest. LOW / MODERATE / HIGH / EXTREME / CRITICAL.

   The joke is structural rather than decorative. The site is funny at the
   bottom of the scale and completely straight at the top, because the person
   reading CRITICAL has a machine showing a ransom note and does not want a
   gag. Humour is aimed at the situation and at Mark. Never at the reader.

   Deliberately NOT the v1 site: that one is light editorial grotesk with
   hairlines and a single cobalt accent. This one is a dark enamel sign with
   a five-colour hazard scale, condensed sign lettering and a mono readout.

   Type   Anton (sign face) · IBM Plex Sans (prose) · IBM Plex Mono (readout)
   Ground Warm near-black, like a sign at dusk
   Scale  Green -> amber -> orange -> red. The colour IS the information,
          so unlike v1 this site needs more than one accent.
