/*
 * QUOTIFY (quote maker): the tool's own components, styled in the site's design language (6 Oct 2026, on the
 * UltraCompress Pro template, after InvoiceForge). Base: /libs/site-pages.css (tokens, Inter and Space Grotesk, buttons,
 * theme toggle, focus rings) and /libs/shared-nav.css (the site's header and footer). This file holds only what the tool
 * itself needs: the toolbar, the collapsible editor sections beside the sticky live preview, the line-item grid, the logo
 * and signature drop zones, the signature pad, the theme buttons, the windows (quotes, clients, catalog, analytics,
 * shortcuts), the settings panel and the toasts. Light is the default; dark applies when <html> has no data-theme. Every
 * class and id the script touches keeps its name, and the variable names the script's markup uses (--gray-500, --warning,
 * --primary-bg ...) are aliases of the site's tokens below.
 *
 * The quote document itself (.quote-preview with its five themes) keeps fixed paper colours on purpose: it is the page
 * the PDF and the PNG are made from and must look the same in both page themes.
