{# Narrative masthead — large italic editorial headline + lede paragraph.

   Mood: Stripe Press / Linear changelog. Serif italic, generous scale.
   Anatomy (top → bottom):
     1. Eyebrow (mono uppercase): SCAN REPORT · started-at · UTC
     2. Headline (serif italic 56/64): synthesized from band + score
     3. Byline (sans, muted): version + target + duration
     4. Lede (sans 19/32, max-width 68ch): one-paragraph synopsis with
        inline anchor links into the sections below.

   Inputs read from the shared view-model payload (no theme-specific keys):
     - scan_id, started_at_label, version, target_ref, elapsed_label
     - aivss_label, band_label, band_class, counts, findings_total
     - is_running, lede_html (Editorial-shared, re-used here)
