v0.13.3

Field-test fixes from a real print session. Thanks for the reports!

Fixed

• Stop from the browser now works while the platform is homing down. The homing sequence didn't service the network at all, so web commands could not reach the printer until it finished — only the physical buttons worked. Now the printer listens every 250 ms during homing.
• 3D print progress survives a page refresh. The slice data now persists in your browser's storage, so an F5 mid-print brings the filling-up model right back.
• Update tab is no longer "dead" for ~10 seconds. Your installed version and the version picker appear instantly; only the "Latest" check (a slow secure connection to GitHub made by the printer) takes its time, with an honest message while it runs. While printing, that check is skipped entirely so it can't disturb the print.
• SD manager is hidden while printing — an empty, disabled block was just noise.

New

• Desktop layout — on a PC-sized window the dashboard now uses two columns (status | controls, 3D progress | SD manager) instead of one long phone-style strip. Phones keep the single column.

Flashing

• Wireless: dashboard → Update → Install latest, or System → Update on the printer, or upload firmware.bin at http://<printer-ip>/update.
• First install over USB: flash firmware-full.bin at address 0x0.
