/* -----------------------------------------------------------------------------
   Font subsetting strategy

   This file declares each weight/style twice under the SAME family name:
   1) a tiny Latin+punctuation subset (@font-face with unicode-range=…)
   2) the full face (no unicode-range) as a transparent fallback

   How it works:
   - The browser loads only the tiny WOFF2 for common text.
   - If a page needs a codepoint outside the subset, it automatically fetches
     the matching full face for that weight/style—no visual jump in metrics.
   - Kerning/ligatures are preserved (we didn’t strip layout features).
   - We serve WOFF2 with font-display: swap for fast first paint.

   Payload impact (potential, with all faces available):
   - Bitstream Charter (4 faces): 45,592 bytes vs 61,160 bytes: 16kb saved = 25%

   Actual page cost is typically lower (only used weights/styles download), but
   this setup substantially reduces worst-case payload while remaining seamless.
