/* ======================================================================
   Nihul Consulting - blog.css
   ----------------------------------------------------------------------
   Loaded AFTER /site.css on /blog/ and on every /blog/<slug>/ page.
   It adds only what the blog needs and never redefines a spec token.

   Everything here is composed from the approved rebrand spec's own
   primitives (brand/landing-share.html): the .hero shell, the .editorial
   paper band with its parchment texture, .hair hairlines, .filter chips,
   .row hairline rows, .btn, Gloock for display, Geologica for text.

   WHAT IT ADDS
     1  .hero--inner   compact dark shell head for a page that is not the
                       homepage (no 90vh, no contour canvas)
     2  .masthead      the blog index title block inside that shell
     3  .hero--post    the same shell with the post's own hero photograph
                       as its ground, plus .posthead (title, rule, byline)
     4  .row--index    the spec row grown a number, a topic chip, a date
                       and a summary line, for the full 15-post listing
     5  .post-*        the reading band: parchment ground, ivory column,
                       Gloock headings, hairline rules, restyled exhibits
     6  responsive     1024 / 820 / 560, matching site.css's breakpoints

   ASSET PATHS ARE ROOT-RELATIVE so a page two levels deep can use it.
