/* =========================================================================
   The Sun Resort Bandhavgarh: Design System
   Theme reference: bandhavgarh-national-park.com (forest green + warm stone)
   with the logo's sun gold as the single accent.

   - Text hierarchy : kicker (sun mark) → heading → lead → body → meta
   - Font           : Plus Jakarta Sans only; hierarchy through size, weight and colour
   - Colour         : ~60% white/stone · 30% forest green · 10% sun gold
   - Repetition     : petal-sun kicker + horizon sweep (both from the logo icon), one image radius, pill buttons
