/* ==========================================================================
   MSP Tutor Registration - Maastricht University house-style skin
   --------------------------------------------------------------------------
   ONE stylesheet, token-driven. Visual identity only - no logic lives here.

   Colour decision (per UM house style):
     • Navy (#001C3D) dominates surfaces, structure and ALL body copy.
     • PRIMARY accent = UM orange-red (#E84E10): the single focal colour -
       claim/CTA buttons, the live "open right now" counts, the filling-up
       progress bar, and the selected state. White text on orange is reserved
       for LARGE/BOLD button text only (~3.8:1); body text is never orange.
     • SECONDARY accent = light blue (#00A2DB): links and quiet tints ONLY,
       never a focal/hero colour.
   Type decision: sans-only. One humanist sans (Inter Tight) for everything;
   display is set by weight + size + negative tracking, not a display face.
   No serif anywhere.
