/*
 * Shared article component library.
 *
 * The migrated posts each carried their own copy of these components inside a
 * per-post stylesheet, so a new article could not reuse them. This is the
 * curated, shared set — built from the same design tokens as the rest of the
 * site — that every article can draw on.
 *
 * Everything here is CSS-only: no charting library, no JS, no canvas. That
 * keeps articles inside the performance budget and, more importantly, keeps the
 * numbers as real text in the HTML where crawlers, screen readers and AI
 * assistants can read them — a chart drawn in canvas is invisible to all three.
