 * Battlecard layout styles.

 * Premium editorial style — generous whitespace, strong typographic
 * hierarchy, restrained palette, subtle accents. All values come from
 * semantic CSS variables defined in src/themes/*.css so theme swaps work
 * without touching this file.
 *
 * Emoji icons in `.bc-cap` cards: rendered as Twemoji SVG `<img>` tags
 * via the `twemoji_url(emoji)` Jinja global, NOT as font glyphs. We
 * tried `@font-face` for Twemoji Mozilla (COLR/CPAL TTF) here, but
 * WeasyPrint's emoji rendering on macOS picks Apple Color Emoji
 * regardless and the same is unreliable on Linux container builds.
 * SVG `<img>` is the only approach that gives consistent flat-emoji
 * output across platforms and between editor preview / PDF.

/*
 * Pagination model: explicit per-page layout (ADR 0002 addendum).
 *
 * The document is composed of N independent `.bc-page` containers,
 * each exactly the size of one A4 page. WeasyPrint only ever inserts
 * page breaks BETWEEN containers (via `page-break-after: always`),
 * never INSIDE one. Sections are allocated to pages in `_preview.html`
 * by the template author — there is no auto-pagination, no `break-
 * inside: avoid` heuristics, no continuation-page padding tricks.
 *
 * The trade-off is that each page has a fixed height (297mm) and a
 * fixed inset (18mm), and content that would overflow is *clipped*
 * (`overflow: hidden`). We treat overflow as a content-too-long
 * authoring bug, not a layout bug — schema cardinality and char-length
 * limits in `app/schema.py` keep content within bounds.
