/**
 * Guide pages — long-form evergreen educational content.
 *
 * Used by the standalone "How to Play Texas Hold'em" page (templates/guide_holdem.html).
 * Article typography (.dl-*) follows .claude/rules/content-standards.md.
 *
 * Colors come from the app's design tokens (base/variables.css) so the page
 * reads as native All-In Poker Tool, not a generic article. Deep-navy surfaces
 * (--bg-card), indigo borders (--border), magenta accent (--accent).
 *
 * Position diagrams reuse components/poker-table.css + the shared renderer;
 * nothing table-specific is redefined here, only the embed wrapper.
