/* VetsLearn v1.1 (Bone/Ink/Rust). Local variable NAMES are unchanged from
   the original dark theme; VALUES now reference the shared tokens in
   sd-tools.css (linked before this file). --accent is intentionally omitted
   here (same name as the shared token) so it inherits the token's rust
   directly. Sanity-flag colors (see .flag / .veteran-flag below) map to the
   token's --warn/--good semantic colors. */
