   Quill UI — Components
   Faithful extractions + recreated paper-sticker system.

   FAITHFUL (DOM/computed-style ground truth from the source):
     · Dotted grid backdrop      · Editorial tab nav
     · Data table                · Buttons (pill / ghost / ink)
     · Row list                  · Mono annotation, display headline

   RECREATED (CSS interpretations of the source's image artwork —
   the source ships these as illustrations, not CSS; rebuilt here
   in the exact pixel-sampled palette):
     · Sticker base + tag / note / price-tag / seal / ticket / toast
