/*
  The Bookshelf of Curiosities — Landing Page V4.0
  Full replacement per DESIGN-SYSTEM.md (repo root). The old V3
  dark-cabinet/frame system has been removed entirely, not left dead in
  this file — per that doc's explicit "do not blend the old system with
  this one" instruction. See README.md for rationale and changelog.

  Every rule below is scoped under .bookshelf-landing so nothing here can
  clash with Material's own styles on this page or any other.

  Colour/font values are sourced from stylesheets/bookshelf-tokens.css
  (the Google Fonts @import lives there too, loaded once site-wide) —
  not hardcoded here. Material's own --md-* variables are overridden in
  stylesheets/bookshelf-material.css, not in this file — that override
  used to live here as a partial, primary-color-only patch; see
  README.md's changelog for why it was split out and completed.

  via layout math that reads this custom property, independent of the

  bookshelf-cursor.js zeroing literal padding/margin-top on the ancestor
  chain (covers the case where the gap is a literal value, not this
