   Extracted from per-theme CSS (step-02/2.a.2b) — byte-identical across
   all 7 extraction-pool themes (especial, especial-light, sols, studio13,

   focused on palette + palette-keyed overrides. Per-theme CSS still loads
   AFTER this file, so any per-theme-specific palette overrides continue
   to cascade correctly.

   Note: some selectors below may also appear earlier in this file as
   legacy _shared declarations — deduplication is a separate follow-up
   hygiene pass (kept out of scope here to minimize behavior-change risk
