   akwOS — shared components
   Every rule here names Tier 2 aliases from `tokens.css` only, so
   the same stylesheet paints correctly on the light product surface
   and inside the dark marketing shell. Nothing below knows which.

   This file exists because ten selectors — .av .feed .grade .ring
   .st .st-todo .tag .tag-green .tag-red .plan-pct — were defined
   twice, in `site.css` and `app.css`, with different rules and two
   incompatible status vocabularies. One definition each, here.
