/* v10.507 / v10.515: page-surface color parity. The shelf / My List
     page uses `#0E0E0E` as its canonical Editorial-Dark base (defined
     at 06-profile.css:1569 under `body.true-dark-mode #mylist-view`).
     Apply the same exact color to the Friends page (`#community-view`),
     the Discovery page (`#discover-view`), and the standalone Activity
     page (`.activity-page`).
     v10.515: escalated to `!important` with maximum-specificity body
     prefixes after a user report that the previous unconditional rule
     wasn't taking effect on the iOS app. Triple-up: cover the bare
     selectors, the active-state selectors, and the body-themed
     selectors so nothing else in the cascade can repaint these
     containers a different color regardless of theme class / load
     order / cached older patch CSS. The `#0E0E0E` hex MUST exactly
     match the shelf's body.true-dark-mode background at 06-profile.css
     line 1566 — if that ever changes, this block needs to track it. */
