/* RideConnect website.

   Brand (PNGs/marketing/m04): Emerald #34D399, deep emerald #059669, Night #0A0D14, Slate #151921,
   emergency red #FF3B30 for SOS and crash content only, regroup gold #DAA520, Poppins SemiBold for
   headlines.

   Interface rules follow docs/Skill Reference/IOS_UI_SKILL.md:
   - The system font for text (Roboto on Android, like the app; SF on iPhone), with tracking and
     leading set per size. Poppins only for headlines, as the brand asks.
   - Light and dark follow the device setting.
   - Translucent chrome over content: the header, and the map pages' panel and bottom sheet.
   - Press feedback on pointer-down. Springs for anything the finger drags (assets/js/sheet.js).
   - Reduced motion, reduced transparency and more contrast are honoured at the end of this file.
   - Spacing in rem, so a larger text setting scales the layout with it. */
