/* ===========================================================================
   Pulliam Plumbing — blog additions
   ---------------------------------------------------------------------------
   Loaded ONLY by the posts and the category archives, after main.css. Kept
   separate on purpose: the 48 hand-built pages must not be able to break
   because of something added for the blog.

   Everything here is built from the existing design tokens — the surface
   ladder, --navy / --brand-red / --steel, --radius-*, --lift-*, --font-display,
   --dur-* and --ease. No new colours, no new radii, no new easing. Anything the
   site already has a class for (chip-list, callout, faq, checklist, prose,
   answer-block, band, section-head) is reused rather than restyled.

   .prose already sets the measure (42rem), paragraph colour, leading and h3.
   It has no h2 and no list treatment, because nothing else on the site needed

/* --- callouts inside prose ------------------------------------------------
   .callout is a navy gradient block, so main.css sets .callout-body p to a
   near-white. But a callout dropped inside .post-body sits inside .prose, and
   ".prose p" has the SAME specificity (0,1,1) while appearing later in
   main.css (line ~4281 vs ~3600) — so it wins, and the copy renders dark grey
   on navy, which is unreadable.

   Both selectors below out-specify .prose p and this file loads after
   main.css, so the callout gets its own colours back wherever it is used. */
