 "visibility": "public",
 "title": "esp-dl's memory ceiling, not its speed, is what rules out on-device detection - and it overflows silently into PSRAM rather than failing",
 "symptom": "The detector fits and runs, so the configuration looks viable. Raising the resize scale to catch smaller or more distant faces makes it about ten percent slower, which reads as a mild cost of a better setting rather than as a failure.",
