v1.1.0

The development update of 2026-09-05, merged into the packaged layout.

• On a screen with less room than the layout's 1024 x 640, the window shrinks to 640 x 400 and the page scrolls, with the bottom panel reachable. The window check opens a 1093 x 574 screen to prove it.
• --check explains that imufusion has no pre-built package for Windows on ARM or Python 3.15; requirements.txt and the fusion extra leave it out there and the numpy attitude filter is used.
• On Linux a serial port that is not yet readable names the dialout group; macOS and Linux distinguish a port another program holds.
• The window check measures a slow frame twice before believing it.
• The catalogue module's docstring names its own file correctly again.
• Three control rows (Spectrum, Separation, Denoise) fit beside their sliders and captions under any font, in the scrolling mode too; the window check gives its standard windows a full-size screen so the off-screen platform's 800 x 600 does not switch them into scrolling mode by accident.
• --check names the course environment mobi311.
