     TEXT COLOR TOKENS — READ THIS BEFORE PICKING ONE
     This theme INVERTS lightness between two zones, so there is no single
     readable text color. Pick the family by WHAT THE TEXT SITS ON:

       • On a CARD / PANEL / TABLE / CHIP (background = --surface):
           use  --text  /  --text2  /  --text3
       • Directly on the PAGE BACKGROUND (background = --bg):
           use  --text-on-bg  /  --text-on-bg2  /  --text-on-bg3

     Surface is LIGHT in dark-theme and DARK in light-theme — the exact
     opposite of --bg — so using a --text* token on the page background
     (or vice-versa) is low-contrast in BOTH themes. This is the #1 source
     of contrast bugs here. When unsure which zone an element is in, run the
     auditor: open the page with ?audit=contrast (or call __auditContrast()
     in the console). See contrast-audit.js.

   TABLE CARD + BADGES
   Promoted from tenant/styles.css (the de-facto standard — `.table-card`
   is used ~100× across pages). Table element rules are SCOPED under
   `.table-card` on purpose: the old copy declared bare `table`/`th`/`td`,
   which leaked out of the tenant bundle and styled every table app-wide.
   Any standalone table (e.g. `.tcq-table`) keeps its own styling.
