/* rmc-print-v2.css — v3.57.0 (2026-05-21)
 *
 * Civic-grammar print layer that EXTENDS (does not replace) `rmc-print.css`.
 * The v1 sheet handles document-class chrome (.rmc-print-document /
 * .rmc-print-invoice) — this v2 sheet adds the brand cascade contract:
 *
 *   1. School wordmark + motto + crest in the running header on every page
 *      (via @page :left/:right margin boxes where supported, plus a static
 *      `.rmc-print-v2__brand-block` injected at the top of long documents).
 *   2. "Confidential · printed YYYY-MM-DD" stamp in the running footer.
 *   3. Watermark `.rmc-print-v2__watermark` for DRAFT / VOID / FINAL stages.
 *   4. Per-tenant brand color cascade via CSS custom properties — falls back
 *      to neutral grayscale when no tenant brand is in effect.
 *   5. Page-X-of-Y counter rendered via CSS `counter()` so it works without
 *      JavaScript even in print preview / headless rendering.
 *
 * Adoption: opt-in. Print templates that want the v2 grammar add the second
 * stylesheet AFTER `rmc-print.css` and wrap content in `.rmc-print-v2`.
 *
 * Token contract: brand color sources `var(--brand-primary)` /
 * `var(--brand-accent)` per the platform brand cascade. No hex literals.
 * Grayscale fallbacks use semantic `var(--text-*)` tokens which serialize
 * print-safely under the @media print reset in rmc-print.css.
 *
 * Accessibility:
 *   - Print is inherently inaccessible — but we keep semantic markup so
 *     screen readers / OCR pipelines (Adobe Acrobat / Foxit) can still
 *     extract structure when generating PDFs.
 *   - Brand-color elements never carry meaning by color alone; the wordmark
 *     and watermark text remain readable in monochrome printers.
