Mattelier v0.26

Mattelier's first public release for Supernote Manta.

• Pressure-sensitive brush with a Light touch → Firm touch response slider.
• Textured tilt pencil, gradual eraser, flood fill, and blending stump.
• Dotted grayscale shading, custom tools, multi-page drawings, and undo/redo.
• Instant tool/shade selection without the extra delayed Android repaint.
• Visible dashed separator between standard and custom tools.

Download Mattelier.apk below and follow the sideload instructions.
Use adb install -r to update an existing installation; don't uninstall first.
The app name is now Mattelier; the application ID and signing identity are preserved.

Tested on Supernote Manta. Nomad and other tablets are not verified. This is an
early app: no layers, zoom/pan, or in-app image export yet; uninstalling deletes
private drawings. SHA256SUMS contains the APK checksum.
