   This block intentionally lives at the END of the file. The earlier
   `@media (prefers-color-scheme: dark)` block was being overridden by
   late-defined light-mode rules (.profile-pick label, .filter-bar label,
   etc.) that have identical specificity but come later in source order, so
   they win the cascade tie-breaker. Repeating the dark-mode rules here —
   AFTER every light-mode rule — fixes the cascade. */
