/*
  Splendid writing modules - shared styles for the reusable article modules.

  This file is ADDITIVE. It holds the newer, self-contained writing modules
  (interactive charts, the editorial timeline). The older module classes
  (.article-fold, .pull-quote, .pop-viz, .rank-list, .ratio-icons, .offer-card,
  .move-list, .reveal, .talking-head, etc.) still live in custom.css and are
  catalogued in writing/MODULES.md. Editing a module here updates every article
  that links this file, because there is no build step and the stylesheet is shared.

  Brand rules that apply to everything here (see our-brand SKILL §5-§8):
  - Data viz palette: Lagoon primary, Poppy + Lake as accents, Daffodil sparingly.
  - Body in Mulish, display/labels in Big Shoulders Display (Hanley substitute).
  - Reduced motion is always honored: no movement, final state shown immediately.

  Load order in an article: bootstrap.min.css -> custom.css -> modules.css.
