/* avatar.css — the guide module's skin. Consumes the landing's --l-* tokens (DESIGN-DECISION section 1)
   and its type scale --t0..--t2 (section 2), with dark fallbacks so the module renders on its own; every colour is on the goldenratiocolors ladder.
   Rules: no viewport media queries here (page-shell only) — the module sizes by @container; states are
   data-state on the root with DISTINCT bar geometry per state; animation exists only inside
   @media (prefers-reduced-motion: no-preference); every target is at least 44 px; visible focus rings.
   landing-R318: the dock's last turn is never clamped (it grows, with an internal scroll only as the
   safety valve for the longest scripted answer); the transcript is a role=log wrapper around an <ol>
   so the list keeps its list semantics and the log its live region. */
