/*
 * Self-hosted Open Sans (issue #22).
 *
 * Replaces the fonts.googleapis.com stylesheet that Enfold injects via an
 * inline script (disabled through the avf_output_google_webfonts_script
 * filter in wofk-front-page-hero.php). The files are the Open Sans v44
 * variable-font woff2 subsets Google serves to modern browsers; one file
 * covers all weights the theme uses (400 and 600), so a single preload
 * makes the font available at first paint and prevents the fallback-font
 * size flash on the front-page hero title.
 *
 * unicode-range values are copied verbatim from the Google Fonts CSS so
 * the latin-ext file is only downloaded when such characters occur.
 */

/*
 * Metric-compatible fallback for the frames before the preloaded woff2 is
 * ready: production pages paint from the Hummingbird cache within ~50 ms,
 * faster than even a disk-cached font fetch, so with font-display: swap the
 * fallback font is briefly visible. The theme's font stack is
 * "open sans", Helvetica, Arial — these faces shadow "Helvetica" with a
 * size-adjusted Arial so that fallback text occupies the same width as
 * Open Sans and the swap is invisible. The ratios were measured per weight
 * against this site's woff2 (Open Sans 600 is narrower than Arial bold,
 * Open Sans 400 is wider than Arial regular); ascent/descent overrides are
 * Open Sans' hhea metrics (106.88 % / 29.30 %) divided by the size-adjust.
