   The v5 component styles, kept alive for the generated case-study

   The v5 token names are remapped onto the v6 palette and typeface,
   so these pages inherit the new look without a template rewrite.

   The generated note and case pages keep their v5 markup and
   inherit the v7 identity from here: one typeface on three
   width axes, sentence-case meta, non-sticky nav, bigger air.
   Appended last so it wins the cascade at equal specificity.

   ponytail: overrides, not a template rewrite. Delete this block
   and the v5 rules above it the day both build.py scripts emit
   v7 markup and can share styles.css outright.
