/* Extra story-card styles loaded by index.html and library.html.
 *
 * Background: index.html and library.html include
 * components/story_grid_card.html but do NOT load
 * static/css/story_card.css. Instead, base .story-card-* rules are
 * inlined in <style> blocks within each template.
 *
 * Rather than continuing to duplicate per-feature additions across
 * both templates, new card styles introduced after Phase 2 live in
 * this dedicated file, loaded once per template.
 *
 * Future: existing inline .story-card-* rules from index.html and
 * library.html may be migrated here as a separate refactor.
