/* Sophia design system — shared base.
   Theme tokens: :root is the LIGHT palette (default + the explicit-light theme). Dark applies
   when the OS prefers dark and the user has not forced light, or when data-theme="dark" is set.
   The toggle (theme.js) writes data-theme on <html> and persists it; a pre-paint <head> snippet
   restores it, so there is no flash. Structural CSS must only ever use var(--…), never a raw hex. */
