# PSRAM (required for 800x480 framebuffer + JPEG decode + local screens).
# 200 MHz speed is gated behind IDF_EXPERIMENTAL_FEATURES on ESP32-P4 —
# at the default 20 MHz the DPI bridge underruns continuously trying to
# feed the panel from PSRAM. 200 MHz gives ~10x more bandwidth and the
# DPI runs clean.

# TCP receive-window + buffer tuning. Earlier attempt under HTTP
# regressed because every /frame opened a fresh socket and we ate
# the slow-start cost repeatedly. Under the streaming pivot the
# socket is long-lived: slow-start happens once, then we run with
# the full window for the rest of the session — which is exactly
# the workload these knobs are designed for. Larger WND lets the
# sender keep more bytes in flight per ACK and pushes our recv
# throughput ceiling up from ~5.3 MB/s.
