   Rust Tool Index — calm, professional, table-driven layout.

   A restrained white/grey palette with hairline borders, barely-there shadows,
   tight radii, per-category icons, a roomy sticky search header, and one table
   per category with friendly green/amber/red status badges. Overrides the dark
   tokens from base.css.
