/* ==========================================================================
   /version-control.php — TAIL_VERSION_CONTROL (V95, Sprint 11 handoff
   "Version Control", part CH). The house style of /vulnerability-scan.php:
   orange prompt headline, Source Code Pro headings, #fdfdfc panels, thin
   teal rules, no rounded cards, emojis or shadows. Order: build line, intro,
   Manual Update Protocol, roadmap (Phase 7–9), changelog (DB rows).
   The changelog body_html (admin/seed HTML) keeps its markup: its lists and
   the v0.0.1 .incident-report render in this page style below.
   Secondary text uses --text-dim (#666, 5.6:1 on #fdfdfc) where the draft
   wrote the off-palette slate #475569.
