/* =============================================================
   crypto-tools shared chrome
   Sidebar + top-bar + ⌘K palette. Load AFTER theme.css.

   Every accent color pulls from --ct-accent / --ct-accent-soft /
   --ct-accent-ghost, so per-tool palettes (body.theme-amber|cyan|red)
   automatically re-tint the active nav item, cmdk hover, and row
   hover without any per-theme selectors in this file.

   The ONE exception: palette pico backgrounds (.p-poly, .p-bybit,
   .p-hash, .p-bitget) are literal per-tool accents, because the
   palette shows every tool side-by-side regardless of current page.
