Replace the full-screen slide-down sheet with two fade-in cards
anchored to the top corners. Quick settings sit top-right,
notifications top-left capped at 60% screen height. Background
scrim reduced to 30%. Redundant clock header and status bar
hidden since both are already visible in the top panel.
Add the committed touch-mode screenshot asset and reference it in the\nREADME. Clarify the project licensing section so the README\npoints at EUPL-1.2 while preserving upstream file licenses.
REUSE CI requires copyright and license info on every file.
CHANGELOG, README, and the two Shift screenshots are original
work, licensed under EUPL-1.2.
