/*
 * Fase 1B — styling for the certification report review document
 * (app/views/certification_reports/exports/_document.html.erb).
 *
 * Hand-written, local CSS — not a Tailwind build, not a CDN font. This file is
 * loaded on the review page today and is meant to be the same stylesheet the
 * Fase 3A PDF job points Chromium at when it renders this partial from a
 * snapshot: the design must not depend on the app's Tailwind pipeline running,
 * only on this file existing on disk (rule 16 in the plan).
 *
 * On screen: a single continuous read, mobile-first (no page concept).
 * Under @media print: A4 reference, a repeating letterhead + footer + BORRADOR
 * watermark via `position: fixed` (Chrome repeats fixed elements on every
 * printed page), and `.no-print` hides every editor control. Browser print
 * pagination is a provisional approximation, not the real PDF (see the plan's
 * Fase 1B acceptance note) — Fase 3A's own Chromium print-to-PDF call is the
 * source of true page numbers via its native header/footer templates.
 *
 * The header/footer `top: 0` / `bottom: 0` (not a negative offset into the
 * page margin) is deliberate — see the comment on
 * .certifier-doc__page-header below for the real multi-page-preview bug this
 * avoids. Fase 3A must use Chromium's own `--print-to-pdf` header/footer
 * templates, never this DOM `position: fixed` trick, for the reasons in that
 * same comment.
