/* Blog post extras (plan ten-blog-post, 2026-11-07). Loaded by blog/_brand_bar.html through cache_bust, after
   blog.css: blog.css is pinned at ?v=20261019 in every post and cached for a year, so a change there would not
   reach a returning reader. Consumes site-tokens.css. Opt-in classes (cost-table--stack, fig--dual,
   toc-phone) only change the posts that carry them.

   Nothing here is under 15px. The floating pieces are built by blog-post.js but take no space in the article:
   the phone bar is fixed, and the desktop card sits in the contents list's own column (layout shift measured 0
   at 1280x720, 1440x900 and 1280x600). */

/* ---------- The floating ask (static/js/blog-post.js builds it) ---------- */
/* Phones and tablets: the homepage's bottom bar, one blue pill on a short fade of the page. */
/* Its content box is the reading column (blog.css: .shell gutter 20px, 16px at 700 and under; .article
   max-width var(--measure), left-aligned), so the pill centres on the text, not on the window: on a tablet the
   column sits left and a window-centred pill hung up to 150px off it (round 2 judge). 100% here is the
   viewport's width. */
