 * Display font.

 * We used to use Gaegu, but it has NO glyphs for accented Latin letters
 * (é, è, à, ç, ü, ñ, ß, œ...) — it only ships ASCII plus Hangul — so every
 * accented French/German/Spanish character fell back to an unrelated system
 * serif and broke the display look mid-word.
 *
 * "Cabin Sketch" is a hand-drawn sketch font that covers the full Western
 * Latin range (accents included) and ships real 400 and 700 weights, so
 * every language renders in one uniform typeface with proper (non-synthetic)
 * bold. We self-host both weights to avoid Google's fragile per-glyph subset
