   Transport terms: /transport/terms/ and the frozen copies at /transport/terms/vN/.
   The pages are written by tools/transport-terms/build_pages.py from
   docs/transport-terms/vN.md, so edit the source and rebuild, not the HTML.

   The look is the approved PDF's (4 Nov 2026): a deep forest cover with orbit
   lines, the short version as light cards on deep forest, pale green reading
   pages, numbered section circles and hanging clause numbers. Every colour is
   a main.css token, so this sheet adds no colour of its own.
   ========================================================================== */

/* main.css gives html AND body overflow-x: hidden. On body that makes a scroll container that
   never scrolls, and a sticky element inside one never sticks, so the contents column would
   scroll away. clip trims the same overflow without being a scroll container. A browser that
   does not know clip keeps hidden, and the contents simply scroll with the page. */
