/* Flashcard Factory — the public landing page.
   Loaded only by index.html, and every rule is scoped under `.lp` so the page
   can have its own palette and type without reaching into the app's.

   The vocabulary is a student's desk: squared paper under the hero, index
   cards with a blue header line and blue rules (the same cards the 404 page
   deals, drawn from the same --card-* tokens in app.css), a ballpoint-blue pen
   for actions and answers, and a highlighter for cloze deletions. The workspace
   mock reuses the product's own classes (.card-row, .slide-row, .chip) rather
   than restating them, so it cannot drift from the real workspace. */
