   Tokens — Arriva corporate palette & type, per brand
   guidelines (Identity Guidelines v2.9, Nov 2023):
   - Arriva Blue #00becd is the dominant colour (60%)
   - Arriva Dark Blue #2d146e is the supporting colour (30%)
   - Bright secondaries (Yellow/Orange/Lime/Purple) are
     accents only (10%) — here: Yellow + Orange, the
     suggested "tonal combination" from the guidelines.
   - Digital palette favours white space: bright, clean,
     high-contrast, not moody.
   - Display type: FF Mark Pro (licensed) → substituted here
     with Poppins, the closest open geometric equivalent.
   - Body type: Calibri, per the guidelines' own online spec.
