   summarise-widget.css
   Floating "Summarise with [LLM]" widget.
   Bottom-right launcher that opens a vertical menu of
   outbound links to ChatGPT, Perplexity, Claude, Grok,
   and Google AI Mode, each pre-filled with a summary
   prompt for the current page.

   Progressive enhancement only: requires JS to function.
   Markup is injected at runtime by summarise-widget.js,
   so a JS-disabled page simply has no widget.

   Visual tokens consumed from /css/shared.css:
     --base, --surface, --elevated, --border,
     --text-1, --text-2, --accent, --accent-hover
