/* Toolbox — landing page styles.
   A black-and-white port of the shadcn/ui design language, written as plain CSS
   so docs/ stays a directory GitHub Pages can serve with no build step.

   It follows shadcn's own conventions rather than inventing new ones:
     · the same design tokens — --background/--foreground, --card, --muted,
       --primary, --border, --input, --ring, --radius
     · the same component recipes — button, card, badge, alert, separator,
       table, accordion, tabs, input, slider, checkbox, progress
     · the "neutral" colour scale with the chroma set to 0, so every surface,
       border and accent is greyscale. Emphasis comes from contrast and
       borders, never from hue.
   Dark is the default; light is a full token override on [data-theme="light"]. */
