+/* ==========================================================================
+   Dark Mode - Great Tables (gt) exemption
+
+   Great Tables output (e.g. pointblank validation reports, gt tables) is a
+   self-contained, light-themed component that ships its own scoped styles for
+   background, text color, and inline code. The global dark-mode rules above
+   target bare `p`/`li`/`code` elements, so they bleed into gt tables and
+   recolor brief text, source notes, and inline code against gt's own white
+   background — leaving light-gray text and amber-on-dark code islands.
+
+   These selectors are scoped under `.gt_table`, so they outrank the global
+   dark-mode rules and hand styling back to gt's own cascade. `inherit` lets
+   text and code pick up gt's intended colors (including status colors) rather
+   than forcing a fixed value, and `transparent` matches gt's light-mode code
+   background. The cosmetic effect is that gt tables render identically in
+   light and dark mode, as designed. See also `table:not(.gt_table)` above. */
