Andrejus	107b9723d5	donut: remove time-based degradation for consistent animation ... Remove three mechanisms that intentionally degraded the screensaver over time, causing it to appear frozen after extended runtime: - Brightness dimming curve (faded palette to 30% over ~15min) - Projection framerate skip (reduced 3D updates from 24fps to 6fps) - Deep sleep after 2hr (dropped to 1fps) The clock drift and matrix text changes already provide adequate OLED burn-in protection.

Andrejus	e686b6396d	Add spinning donut screensaver with matrix rain ... Terminal screensaver written in C, triggered by tmux lock-after-time (180s idle), bind S, or `donut` alias. Features: - Spinning torus with precomputed trig tables, randomized rotation - Matrix rain overlay — donut luminance colors the rain characters - 64-shade teal foreground palette with gradual dimming over time - Chunky 7x5 clock with shadow, blinking colon, periodic drift - Activity time display below clock (read from heartbeat state file) - Rim lighting and ambient occlusion on donut edges - RLE escape state machine — only emits SGR on shade transitions - Row-skip rendering — empty/leading/trailing regions use cursor jumps - Projection runs at adaptive rate (24fps bright, 6fps dim) - select()-based frame pacing, deep sleep after 2hr (1fps) - Resume detection — flushes stale PTY output after sleep/lock - Mouse click to quit (SGR + X11 protocols, release filtered) - write_all() retries partial writes, SIGPIPE handled gracefully - Alternate screen buffer preserves shell scrollback Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>	2026-02-27 16:56:44 +00:00
