locale defaults to "auto" and resolves from the proxy egress country the same
way timezone does - it reuses the egress IP, maps the country to a BCP-47 locale
with the offline mmdb, and falls back to en-US. prefs emit juggler.locale.override
(the full Accept-Language list) so the binary keeps navigator.languages and the
Intl default locale in sync.
The audio fingerprint noise is off in the baseline. Font prefs match the new
binary: the sampled whitelist drives font.system.whitelist, system-ui is Segoe
UI, the bundled fonts are activated, and the CSS generics are pinned to Windows
defaults so they resolve on a non-Windows host too.
- BINARY_VERSION -> firefox-12 (self-calibrating font widths, per-family canvas
distinctness, render-noise that preserves solid reference renders).
- font_pool: the standard Windows fonts (Calibri, Franklin Gothic, Gadugi,
Javanese Text, Myanmar Text) move from the per-profile optional set to core,
so they are always present and the detected font set matches a real Windows
install on every host. Defensive dedup in derive_font_prefs.
- GPU persona applied on every platform (Linux/macOS present a coherent Windows
GPU + WebGL params); pool re-rooted on a real-device GPU mix; render seeds
recalibrated.
- prefs: emit absolute per-family font widths that the binary self-calibrates.
- geoip: always pull the latest mmdb via the releases/latest permalink, checked
each launch, offline-safe (no pinned tag that can 404).
- tests: per-font canvas distinctness, solid-readback purity under render-noise,
always-present standard-font invariant, no duplicate families.
