v2.8.0

What's New

• Seeed Studio reTerminal E1004 support — a new supported board: 13.3" E Ink Spectra 6 full-color e-paper (1200×1600), microSD (SPI) + internal-flash storage, SHT40 temperature/humidity sensor, PCF8563 RTC, and battery monitoring. Buttons: Refresh = wake, Next = rotate, Prev = clear. The project now supports 5 boards.

Improvements

• 10-minute auto-sleep window during first-time setup — more time to scan the QR code and provision WiFi from the companion app before the device sleeps (normal operation unchanged).
• Web UI keeps the device awake while the tab is focused, with an "asleep" hint that names the board's wake button.
• Redesigned landing/web-flasher page (lists all supported boards) and added companion app store links.

Fixes

• Security fix (V-002, #96).
• process-cli: fixed all-black S-curve output caused by a variable-naming mismatch (#95), and honored the renamed --scurve-* flags.
