+// firefox-fourier — RK3399 V4L2-stateless HW-decode default prefs.
+//
+// The patch series (0001..0004) builds the VAAPI / V4L2-request routing
+// path through libavcodec, but the resulting code path is gated by three
+// other prefs that are 'false' upstream because the relevant probes don't
+// fire on panfrost EGL or trip the Intel-tuned cost heuristic. Without
+// these, firefox-fourier silently SW-decodes on a fresh profile despite
+// having all the unlock patches applied.
+//
+// Filed via marfrit/marfrit-packages#8 — see that issue for MOZ_LOG
+// evidence on fresnel (Pinebook Pro / RK3399).
+//
+// These are *vendor* defaults: lower precedence than user.js and
+// about:config user prefs. Power users who want to disable HW decode for
+// debugging can flip them in user prefs without touching this file.
