/* ============================================================================
   Aurora surface kit — shared by the dashboard shell and the public marketing
   site (linked from views/app-shell/*.ejs and views/layout/public-layout.ejs).

   Single source of truth for the presentational surfaces that both the Vue
   dashboard and the server-rendered marketing mockups draw with:
     1. tokens         (.aurora-surfaces scope, --surface-* custom properties)
     2. product header (was ProductHeader.vue <style scoped>)
     3. filter tabs    (was AuroraFilterTabs.vue <style scoped>)
     4. cards, kicker, pills, KPI tiles, AI callout, incident queue
                       (was SentimentPage.vue <style scoped>)
     5. card subtitle + trend line chart (trend-*)
                       (was SentimentPage.vue <style scoped>)

   Naming: shared surfaces use neutral aurora-* classes and --surface-* tokens
     aurora-card (+__header/__title/__kicker)   panel card
     aurora-pill (+--badge, tone-*)             status / severity pill
     aurora-kpi-row > aurora-kpi-hero | aurora-kpi (+--risk)   KPI tiles
     aurora-callout (+--primary, __icon/__body/__headline)     AI callout
     aurora-queue-panel > aurora-item-list > aurora-item-card  record queue
     aurora-surface-stack                       vertical section stack
   Only shared selectors live here (aurora-*, trend-*, product-header,
   aurora-filter-tab). Page-specific modifiers (e.g. aurora-card--brief) and
   page-only classes that happen to share declarations stay in the page's own
   scoped CSS, so nothing here can leak onto another page.
   Rules are plain global CSS: Vue pages that keep scoped overrides for these
   classes still win on specificity, which is intended.
