/* ============================================================================
   insight.css - Insight Engine "noticed" surfaces (S10-IE-FE-1)
   ============================================================================
   Two render targets, one shared card anatomy:
     1. .insight-band       per-page precision band (docked to a product page)
     2. .insight-boardroom  /today recall panel (everything noticed, one place)

   Authority: templates/mockups/sovereign_insight_band_mockup.html (canon,
   S14-REDESIGN-W2). Class names are carried verbatim from the mockup; the two
   root containers are namespaced (.insight-band / .insight-boardroom) and the
   generic internals (.live, .seg, .stream, .band-*, .br-*) are scoped under a
   root to avoid collision with the shipped .live rule in governance.css.

   Cascade: wrapped in @layer components to match sovereign.css / ui-kit.css.
   Tokens: reuses shipped tokens (--surface-*, --cream, --ink-ghost, --ink-muted,
   --ink-label, --terracotta*, --success/--warning/--danger/--info, --border,
   --divider, --radius-*, --ease-*). Adds four token families the mockup
   introduced (--telemetry, --border-strong, the semantic -muted tints, and the
   AA-lifted --signal-*-text tints), with [data-theme="light"] overrides so text
   clears AA over the pale light-mode fills.

   Charter invariants held: terracotta is action-only (act-on / promote / active
   filter / focus / quiet-link hover); signal type carries state via semantic
   spine + tag; unseen state rides the neutral cream/ghost family; Instrument
   Serif appears only on the observation sentence.

   NOTE (data contract, DECISION-FOR-CRITIC): the Wave A engine emits no
   structured evidence records on insight_events. The evidence trail therefore
   renders confidence-only (a single conf chip) when confidence is non-null, and
   is omitted entirely otherwise. No "Noticed in" record chips are fabricated.
