/* Optimyst blog (spec §4, §8.1; plan T12, I-19).
   1. The mock-ups' <helmet> styles (index + post, merged; `.op-photo*`/`.op-veil` dropped: D-7).
   2. Renderer classes (I-16, ER-1): the post mock-up's inline declarations moved to classes.
   3. D-5 styles for elements the mock-ups lack.
   4. Link/span stand-ins for the mock-ups' <button> chips and pager (D-1).
