/**
 * Homepage "Where to Go, When" seasonal planner
 * (Views/Home/_SeasonalPicks.cshtml, js/apps/home/seasonal-picks.js).
 *
 * Plain CSS - no Tailwind build step. The section's tint follows the
 * selected season ([data-season] swaps four custom properties; the
 * background colour fades between them). Picks are tilted postcards with a
 * postmark stamp; they straighten on hover and deal in one by one when a
 * season is chosen. Active tab uses the brand red like every other button.
 * Logical properties keep it correct in RTL; motion stops under
 * prefers-reduced-motion.
