/* TitrateLab — article visual + micro-interaction component system.
 *
 * Reusable, markdown-droppable data-visualization + micro-interaction
 * components for long-form research articles rendered through
 * templates/research_article.html. Progressive enhancement: every
 * component ships a server-rendered textual/tabular fallback inside its
 * markup (see article-enhance.js), so no-JS readers, crawlers, and screen
 * readers always get the real numbers. JS only makes the data vivid.
 *
 * Built on the shared design tokens in titratelab_tokens.css — palette,
 * spacing, radii, and the mono/serif/sans families all reuse --tl-* so
 * these components evolve the existing dark editorial aesthetic rather
 * than introduce a new one.
 *
 * Accuracy firewall: all data graphics are CODE-GENERATED from the real
 * numbers embedded in the markup. No AI imagery touches anything with data.
 *
 * Conventions (drop any of these into any article's markdown body):
 *   <figure class="tl-chart" data-chart="evidence-map" data-series='[...]'>
 *   <figure class="tl-chart" data-chart="bars"         data-series='[...]'>
 *   <div class="tl-grade-meter" data-grade="..." data-scale="...">
 *   <span class="tl-countup" data-to="16">16</span>
 *   <... class="tl-reveal">                  (scroll-reveal any block)
 *   <span class="tl-cite" data-tip="...">...</span>  (hover/focus tooltip)

 * A restrained set of editorial "rhythm" primitives that break up long
 * walls of prose without shouting: a punchline highlighter, a set-off
 * pull-quote, an inline stat chip, a per-section takeaway box, and the
 * "evidence snippet" receipt cards that replace the old evidence-map
 * figure. All markdown-droppable, all on the same --tl-* token system.

 * stays a quiet single-phrase wash. No JS required for any of these
 * (purely declarative styling) — they degrade to plain semantic HTML.
 *
 * Conventions (drop into any article's markdown body):

 *   <blockquote class="tl-pullquote">…</blockquote>  (or .tl-pullquote div)
