 /* ==========================================================================
-   COMPATIBILITY ALIASES — the app's historical names, pointing at the system.
-
-   These exist so ~55 components keep working while they migrate to --fs-*
-   one at a time. Every one is a plain var() reference, which is what lets this
-   block be declared ONCE: when [data-theme="light"] moves --fs-surface-page,
-   --color-bg follows, because the alias resolves at use time.
-
-   That is why this file lost 48 of its 60 dark-mode overrides — they were all
-   restating relationships the aliases now express directly.
-
-   Removing this block is a rename sweep across the components, tracked
-   separately. Nothing new should reference a --color-* name.
+   The compatibility-alias block that lived here is GONE (#2533). It let ~55
+   components keep their historical --color-* names while theme.css was
+   repointed at the design system; the rename sweep it promised ran on
+   2026-08-08 and every component now references --fs-* directly. Do not
+   reintroduce app-local alias names — the design system's tokens are the
+   vocabulary, and check_snippets_against_design_system can only see through
+   names the system actually declares.
