/* PromptShare — one stylesheet for the whole site.

   Idea: the site teaches people to read prompts, so a prompt is set like code
   under review: monospaced, with each influential phrase marked in the colour
   of the job it does (subject, light, camera…). Chrome stays monochrome so
   those marks and the media are the only colour on the page.

   Contents
     1. Fonts and tokens (light and dark)
     2. Base
     3. Header, footer
     4. Controls: buttons, chips, segmented, fields
     5. Prompt marks and role legend
     6. Cards and grids
     7. Browse pages (Images, Videos, Search, Words)
     8. Plate (one output with its prompt)
     9. Games
    10. Home (new) and Home (three panels)
    11. Document pages (About, Terms…)
    12. Popover, toast, loading
    13. Motion and page transitions
