   Shorey — AI assistant  ·  /assistant
   Translated from Shore Pass Design › ai-assistant.jsx › AIAssistant + ShoreyLogo.

   The prototype is a 340×500 floating panel: gradient header, scrolling message
   list with 80%-wide bubbles, a "Try asking:" prompt list and a pill composer with
   a round send button. Here it is a whole screen, so the panel fills the phone
   viewport; at ≥1024px it collapses back into the bordered, rounded card the
   prototype draws.

   Every rule is scoped under .scr-assistant. Colours come from the design tokens,
   so dark mode is free — the one literal is the gradient's second stop (#4A8FE7),
   which no token covers.
