/* ==========================================================================
   Weekly Challenge — public page, archive, and TV view (BC-1419)
   ==========================================================================
   Scoped to .ch so nothing here can leak into the site chrome (the retired
   /fathers-day page taught that lesson). Design follows the BC-1399 asset
   pack: paper cards pinned and taped onto a dark lounge backdrop, Montserrat,
   Copper #C84F36 / Sunflower #F7B32B / Graphite #2A2A2A / Off-white #EEF0F2.
   Playful on purpose. This is a challenge, not an announcement.
