   Every value is a token on .wmti, and every token falls back through the host
   theme first:

       --wmti-surface: var(--wt-surface-2, #171d2e)

   On a site that already has a token layer the index simply adopts it - dark
   mode, accent colour and radii included - with nothing to configure. On any
   other site the literal after the comma applies. That is why there are no
   hardcoded colours below this block: overriding one token restyles every
   component that uses it.

   Scoped entirely under .wmti. The plugin never styles a bare element.

   CSS columns rather than grid, on purpose. A grid would give every group its

   flow into the next column the way a printed index does, which is what the

     the setting is a ceiling and the viewport decides the rest - no breakpoint
     list to keep in sync with it.

     THIS REPLACED A LADDER OF FIXED CAPS, which was wrong. Capping at 4 below
     1400px meant a 1280px laptop - most laptops - could never reach 5 or 6
     however the plugin was configured, because min(6, 4) is 4. The bug was
     invisible on a wide monitor and total on a normal one.
