   All Z Well Gas

   Hand-written for this site. No framework, no build step.
   The only outside resource is the IBM Plex Sans webfont (two weights).

   Colours are measured off assets/brand/allzwellgas-logo.png:
     ink     #0A1139   the "GAS" lettering, used for text
     blue    #082E9C   "ALL" / "WELL", used for headings, links, buttons
     flame   #F64B06   the "Z", used only for small accents (icons, focus)

   The logo's "GAS" is near-black, so the logo only sits on white or the
   light tint. Orange is never a background.

   The file follows the page from top to bottom:
     tokens · base · placeholders · buttons · site head · hero · facts ·
     sections · services · our work · photo viewer · about · team ·
     contact · site foot
