/* Renéra · Post Detail — long-form single-post article page (desktop).
   Recreates the Claude Design "Post Detail (Desktop)" mockup inside the live
   theme. Loaded after homepage.css (shared chrome + design tokens) and posts.css
   (the .rn-post-card chrome reused by the Related grid). Mobile devices layer
   post-detail-mobile.css on top via the .rn-m body class.

   Key adaptation vs the prototype: the prototype hand-tagged each <h2> with a
   data-num attribute and wrapped its text in a <span>. Real the_content() markup
   has neither, so headings here auto-number with a CSS counter and the numeral is
   absolutely positioned to the left — no grid-splitting of the heading text.
   All colours come from var(--renera-*) tokens; never hard-code hex. */
