   agent-heartbeat.css — Shared "agent is alive" indicator (static, no spin)
   ==============================================================================
   Global stylesheet — shared between AgentStatusSurface (compact row) and
   MessageBubble (bubble surface).

   P9-S (2026-05-21): the rotating-ring animation was removed across all phases.
   The MM:SS elapsed counter in the bubble header is the sole "agent is working"
   signal during a turn; the streaming shimmer (agent-narrator-answer.css)
   covers the per-paragraph progress. The static colour-coded ring stays as a
   quiet phase-state indicator (blue=working, yellow=awaiting, amber=interrupted,
   red=errored, gray=cancelled) — informative without competing for attention.

   .att-card-prev-pill — "Previously uploaded" dedup indicator
   ==============================================================================
   Rendered inside .att-card-body on both the pre-send chip (ChatInput) and the
   sent-message card (MessageBubble). One global rule, no per-component
   duplication. Quiet gray styling so it never reads as an error — it's a
   neutral acknowledgement that the agent already has this content and skipped
   re-extraction. Tooltip explains the meaning on hover.
