Environment

Discussion

Ferreo

Fixed and pushed in otter-wayland 869cc93 and otter-term ce8cae8. Shared seat handling now exposes exact axis_value120 wheel detents (with legacy axis_discrete fallback), and otter-term uses those exact steps for scroll_rows_per_notch instead of accumulating imprecise continuous axis pixels. Smooth touchpad scrolling still uses scroll_fixed_per_row. Added regressions for detent routing and residual-free 120-unit accumulation. Verified with ReleaseFast tests in both components and a ReleaseFast otter-term app build.
