- Clear WIFI_CONNECTED_BIT on disconnect so wifi_is_connected() stops reporting a link that is gone; the weather task's reconnect path was dead code without it. - After the 8 fast retries are spent, retry every 30s via an esp_timer forever instead of giving up until power cycle. FAIL_BIT now only unblocks the boot-time wait and is cleared on reconnect. - Start the weather task even when the boot-time connect times out -- the background retries may still bring WiFi up later. Only an empty SSID skips it. - Round temperatures with lroundf(): the old +0.5f-and-truncate rounded toward zero below 0degF (-10.6 displayed as -10). - Drop the stale single-framebuffer "Partial-mode flush" comment in display_rgb.c, fix the README paragraph claiming the bounce buffer is disabled (it is enabled and load-bearing), and correct the sdkconfig.defaults header to N16R8/16MB.
