/*
 * Charting Mode — self-hosted typeface bundle (April 2026).
 *
 * The Charting Mode modal opens out of the dashboard-editorial Watchlist
 * toolbar. Its editorial typography is `Source Serif 4` (italic + roman)
 * for headlines/kickers; the body falls back to the global system stack
 * already loaded by the dashboard.
 *
 * We ship four woff2 files (Regular + Italic, Latin + Latin-Ext) sourced
 * from Google Fonts so we never make a runtime request to fonts.gstatic
 * when the modal opens. Total payload: ~76 KB across all four files,
 * served only when the modal mounts (the <link rel=stylesheet> in _app
 * preloads the CSS shell which is ~2 KB; the woff2 files are then
 * lazy-fetched by the browser the first time a glyph is requested).
 *
 * font-display: swap so the system serif renders instantly while the
 * woff2 swaps in without blocking paint.
 *
 * SCOPING: every selector that wants Source Serif 4 must live under
 * `.charting-mode` (set on the modal root). This guarantees the rest of
 * the app cannot accidentally cascade into Source Serif 4 if a sibling
 * stylesheet lands later.
