   COMPONENTS.CSS — every reusable public-site component.
   Extracted out of the old inline <style> blocks in index.php
   and includes/footer.php (brief §21: no thousands of lines
   living inside page templates), then extended with the new
   premium pieces: hero 3D stage, featured-deals rail, category
   glass panels, coupon flip-reveal, toast.

   Depends on the token layer in theme.css. Contains NO colour
   literals except where a value must stay identical in both
   themes (semantic greens/reds and pure white text on accent).
   Ordering: buttons -> hero -> stats -> section shell -> cards
   -> code reveal -> marquee -> pills -> zones -> rail ->
   categories -> filters -> newsletter -> footer -> overlays.
