Free heap

RAM headroom on the MCU; dips under load.

Wi‑Fi to the world

Signal at the cabinet — not your device.

Every bit of data needs energy.

Browsing is light, but not free. This project keeps the footprint visible — smaller payloads when reserves fall, honest limits when the sky goes grey.

What happens when energy gets low?

Full sun mode

Normal images, live metrics, full resolution.

Low power mode

Fewer animations, lighter assets, cached pages.

Minimal mode

Text-first layout, delayed refreshes, quiet feeds.

Sleep

Site rests until dawn or enough charge returns.
