/*
  SweetSpot Heating & Cooling: coming-soon site
  Brand: SweetSpot Brand Guide v1.0 (Oct 12, 2026)
  - Brand colors: Orange #FF5A00 and White #FFFFFF only.
  - Ink #211A16 is functional: text, UI icons, borders. Never a brand accent.
  - White text on orange only at 19px bold / 24px regular and up (large text).
  - Plus Jakarta Sans 400/600/700/800, self-hosted (SIL OFL).
  - Logo files are the approved masters, used unaltered as <img>.
  - The comfort dial is only ever moved as a whole (translate) or scaled
    uniformly. It is never rotated, recolored or redrawn, and the dot stays
    at 12 o'clock.
