/* =========================================================
   Tridentu Course Page - Premium Redesign (NO BG IMAGE)
   Fixes:
   - Hero gradient is full-width and starts smoothly (not “from nothing”)
   - All links/buttons get consistent styling (no unstyled anchors)
   - No overflow (no 100% width + margins conflict)
   - Clean, modern, minimalist, premium feel
   Requirements:
   - general.css stays unchanged
   - your HTML classes: hero, hero-inner, hero-main, hero-aside, panel, badges, badge, cta, level-nav, level-step, map, card, lvl, block, grid-3, takeway, band, etc.
