/* =========================================================
   BLOG ARTICLE  (src/styles/blog-article.css)
   ---------------------------------------------------------
   The post template rendered by includes/blog-post-template.php.

   ONE COLUMN
   The hero lockup, the body copy, the wide figures, the end cap
   and the comment thread all sit in the same --bp-measure column,
   so a reader's eye follows one left edge from the headline to
   the last reply. Only an inset figure sits narrower, on purpose.

   FOUR VARIANTS, ONE ARTICLE
   The template stamps .bp-article--text | --single | --duo |
   --rich from the number of figures the post supplies. Every
   variant shares this file's measure, type scale, spacing
   rhythm, hero lockup and end matter — only the figure
   choreography changes:

     --text    0 figures. Drop-cap lead and a red rule on each
               h2 so the page keeps a cadence without images to
               break it up.
     --single  1 figure, spanning the measure.
     --duo     2 figures: first wide, second inset and floated.
     --rich    3+ figures alternating wide/inset; two adjacent
               figures render as a 2-up pair instead.

   SIGNATURE
   The short red rule the site puts under every page title
   (.support-head__title::after) is reused here as a reading
   progress bar pinned beneath the nav. Same device, new job:
   on an article, length is information the reader wants.

   Defensive notes: m072224.css sets global
     p, li { line-height: 2.2rem; font-size: 1.2rem;
             letter-spacing: .03rem; color: var(--c3) }
     ol li { list-style: decimal; list-style-position: inside }
     ol    { display: grid; grid-gap: .5rem }
     b, strong { font-weight: 400; letter-spacing: .07rem }
     h1 { font-size: 4rem; font-weight: 200; uppercase }
     a  { color: var(--c4) }
   Class selectors (0,1,0) out-rank all of those (0,0,1 / 0,0,2),
   so each rule below simply restates what it needs.
