/* Article integrity guardrails — responsive owner v2 — 2026-08-18
 * Production contract:
 * - Enqueued after plugin-overrides (priority 1001) and content-hash versioned.
 * - One visible canonical H1 from single.php; source-body H1 remains portable but hidden here.
 * - Rail stacks through 1279px and becomes a bounded 260–320px sticky rail from 1280px.
 * - Technical lists/references cannot create intrinsic tracks wider than the article canvas.
 * - Dense mobile tables and code blocks scroll inside their own regions instead of leaking into the page.
 * - Prose keeps a readable measure while figures/PDFs retain the wider research canvas.
