/* ============================================================
   demo.css — the interactive app demo on the homepage

   Everything is prefixed .ttd- so it can never collide with the
   page. Colours come from site.css / home.css tokens; the few
   values defined here are the ones the desktop app fixes in its
   own stylesheet (terminal palette, chrome surfaces).

   Sections:
     1. Section shell + tokens   8. Launch deck
     2. Title bar + tabs         9. Kanban board
     3. Summary bar             10. Overlay: modal, drawer, toast
     4. Splits + tiles          11. Tour strip
     5. Terminal                12. Shared chips, pills, type
     6. Agent tiles             13. Responsive
     7. Web tile                14. Reduced motion
