/* astrochart — shared print stylesheet.
 *
 * Single source of truth for paper output. Used by three places:
 *   1. shell.py @media print (every reading page)
 *   2. interactive.py @media print (the chart page)
 *   3. pdf.css (the dedicated WeasyPrint document path)
 *
 * Theme-aware via the existing CSS custom properties — the active
 * theme's accent (gold/blue/etc.) carries onto headings + the brand
 * mark, body copy stays near-black for legibility, and decorative
 * backgrounds collapse to white to spare toner.
 *
 * If a page needs a print-specific override (e.g. the chart page
 * needs `.chart-stage svg .chart-bg { fill: #fff }`), that lives at
 * the calling site; this file holds only the cross-page rules.
