/*
 * The blog article template.
 *
 * Every post - 2021 prose, 2025 course posts, the 2026 designed guides -
 * renders through this one stylesheet. Per-post <style> blocks are removed
 * at render (PE_Post_Html), so there is nothing to fight. Hand-written,
 * tokens only.
 *
 * Designed articles carry markup we cannot know the classes of, so their
 * components are recognised by what they contain: a block that holds a
 * bulk-buy or course link is a call-to-action card; a link standing on its
 * own inside a block is a button; details/summary is an FAQ.
