/* B3 · October 17, 2026 edition layer. Builds on the October 5 dark system:
   same tokens, same wrap, same buttons. Adds a cinematic cover, a UTC provenance
   strip, a disclosure-timeline rail, a severity table, a split "two sides of the
   glass" card, a pull quote and numbered checklists. No inline styles anywhere. */
