/*
  Subject list:
  1. QA29 Buku Shop - fictional neighbourhood indie book shop
  2. Cream, warm amber orange, paper white, deep book-ink charcoal
  3. Fiction, non-fiction, children's titles with RM pricing
  4. Malaysian Ringgit (RM), RM5 flat shipping with free threshold at RM100
  5. Reading notes, author shelf cards, bookmarks, paper receipts
  6. Device cart persistence across page reloads
  7. Clear demo notice: sample catalogue, orders are not actually processed or sent
  8. Responsive mobile ergonomics: thumb-friendly quantity controls, clear live cart panel

  The Idea:
  "On this site, an indie bookshop's paper bookmark and shelf tag system becomes the interactive catalogue and tally slip."
  Competitor check: Generic e-commerce uses standard generic retail tiles and modal checkouts; QA29 Buku Shop uses bookstore shelf tags with live category tabs, tactile +/- tally counter, and clear shipping meter.
