/**
 * Long-form "learn" guide pages — the shared component styles every learn/*
 * block renders against, kept in one stylesheet instead of duplicated across
 * the blocks that share them (callout notes, checklists, two-column splits).
 *
 * Values here are transcribed from the approved design for these pages, so
 * they intentionally use literal px/rem numbers where that design differs
 * from the site-wide tokens (label tracking, card radius) rather than reusing
 * a token that would drift the page away from the design.
 *
 * Requires base.css first (.container, .sec-label, .btn, .glow, .stat-chip).
 * Loaded on the front end only for posts using learn/* blocks (see
 * settings/enqueue.php) and inlined into the editor canvas via
 * add_editor_style().
