/* Design: pure Cursor (cursor.com), chosen by the user on 2026-10-14.
   Colours are Cursor's own theme values (--color-theme-*): warm off-white #f7f7f4, ink #26251e,
   cards stepping darker, borders/text as ink at 2.5–60% alpha, accent orange #f54e00 used sparingly.
   Type (user's choice): IBM Plex Serif 22px for the conversation; the UI is a smaller sans (Inter);
   mono for tool steps. Corners stay sharp (3px) per the user's standing preference. */
