/* ==========================================================================
   ms-hub.css — Middle School Success Center
   Hub page sections + the shared game shell used by all five resource games.
   --------------------------------------------------------------------------
   Every class here is `ms-` prefixed. This file consumes the tokens declared
   in /assets/css/y2-tokens.css and never redefines them, so the hub inherits
   any future palette change for free. It deliberately does not touch y2-,
   cc-, sv-, sc-, pc- or demo- selectors.

   Two audiences share one stylesheet. The hub sections (ms-hero, ms-why,
   ms-resources, ms-bridge, ms-signup) are parent-facing and stay flat and
   typographic. The game shell (ms-game-*) is student-facing and is allowed
   more play — bigger radii, emoji, a progress rail — but only ever inside the
   same three-colour palette. There is no second theme here.

   Contrast notes, measured against WCAG 2.1:
     ink   #14264C on paper #FBFAF6  → 13.9:1
     ink   #14264C on pencil #F5B91E →  7.6:1   (chips, buttons, badges)
     white #FFFFFF on ink #14264C    → 14.4:1
     ink-60 #5A6785 on paper         →  5.6:1
   Pencil yellow is NEVER used as a text colour on paper or white — it fails
   at every size. It is a surface colour only, always carrying ink text.

   FOOTER

   This duplicates the shape of the legacy .footer from styles.css rather than

   over 90% of it went unused on this page — it was being loaded for the
   footer and nothing else. Restating ~40 lines here removes the largest
   blocking stylesheet on the page. The visual result is the same footer.
