/* ============================================================
   StandaloneSummary — unified hero + ledger summary card.
   Shared visual chrome for the post-completion moment across
   reading, flashcards, writing and grammar. Mirrors the iOS
   QuizCompletionHero / SessionCompleteCard pattern: tier headline,
   weekly-progress pill, ledger card (gradient stroke + paired
   shadow), monumental TOTAL row, primary 3D-press CTA, secondary
   outline + tertiary text link.

   Class prefix is `.fs-*` for historical reasons — these rules
   used to live in flashcards/styles/flashcards.css. JS that builds
   the markup is static/scripts/standalone_summary.js.
