   Custom CSS — Override any default styles here.

   This file is loaded AFTER all other stylesheets, so your rules take
   precedence. It is never overwritten by spec-up-t updates.

   PDF-specific classes (apply only in the generated PDF):

   .pdf-cover          — the cover page wrapper (title, logo, description)
   .pdf-logo-container — the <a> element wrapping the logo image
   .pdf-logo           — the logo <img> itself
   .pdf-title          — the <h1> specification title on the cover
   .pdf-description    — the <p> description text below the title
   .pdf-toc            — the table-of-contents container
   .pdf-toc-heading    — the "Contents" heading inside the TOC
   .pdf-toc-list       — the <ul> list of TOC entries

   Examples:

   Make the cover logo smaller:
   .pdf-logo { max-width: 80px; }

   Shrink the cover title font:
   .pdf-title { font-size: 2rem; }

   Make the description italic and grey:
   .pdf-description { color: #666; font-style: italic; }

   Reduce TOC font size:
   .pdf-toc-list { font-size: 0.9rem; }

   Web view — make the header logo bigger:
   #logo img { max-height: 60px; }

   Target PDF only (body gets class "pdf-document" during PDF generation):
   body.pdf-document { background: white; }

   Target HTML view only:
   body:not(.pdf-document) { background-color: #f5f5f5; }
