/* TAB website system: "Keycap + The step" (Sal picked his mix of directions 1 and 3 on 2026-10-25, review page
   x_branding/tools/review/tab-widget.html; the rulebook is x_branding/tools/review/tab-rulebook.html). It styles every TAB
   page on the website: the TAB News hub and issue pages (core/post-renderer.js, template "tab"), /tab-news, the strategy
   landing and /academy.

   The idea: the TAB block is a key. So everything you PRESS is a key: iris with graphite letters (the logo's own colours) and a
   deep iris lower edge that presses down. The step inside the B (capability going up) marks WHERE YOU ARE: a rising underline
   under the active nav item and section titles, and the iris staircase from the kit's collages on lead images and the join box.

   Colour jobs (kit chapter 03): graphite and chalk carry the page; iris is the signature (the keys, the step, the collage);
   deep iris is links and highlighted words in light mode (#C1B3FF in dark); fog orders quiet bands. Text is graphite/chalk and
   the kit's tinted greys (#423A50, #635B73 / #DDD5E9, #C0B8D1), never a neutral grey.
   Type (kit chapter 04): Space Grotesk only, 300 to 700 (never 800): display 700 at -3.5%, headings 700 at -2%, body 400,
   labels 700 caps at 12%.

   Four deliberate website decisions that differ from the kit (recorded on the rulebook and in doc 141):
   1. The primary button is iris with a graphite label (the kit's "on accent" pair, 5.37:1) in both themes; the kit gives
      actions to deep iris (light) and #B5A5FF (dark). Text links keep the kit's link colours.
   2. Iris appears more than "once per surface": on every key, the step and the collage. Body text never uses it.
   3. Light pages sit on the kit's elevated tone #EEEAF5 with fog bands and firmer card edges #CBC2DA (Sal's contrast
      decision for the TAB landings, 2026-10-25); chalk #F6F4FA is the paper inside cards and fields.
   4. The key's lower edge is a depth cue on buttons and cards only, never on the logo (kit: no 3D or shadows on the mark).

   Dark is the default; light follows body.light-mode (the class the site's clock theme sets) or [data-theme="light"].
   Every class is prefixed tb- so it never collides with page or agent CSS. Fonts load separately: /files/tab-brand/fonts/
   fonts.css on the site, ../fonts/fonts.css in the kit. No em dashes in copy. */
