// SFLP rules: // 1. No texture fetches unless necessary. // 2. No loops longer than 8 iterations. // 3. No matrices — use signed distance fields. // 4. Branchless where possible. // 5. Fit in 80 columns, 32 lines. // 6. One uniform block max. // 7. Output must run on Mali-400 / Adreno 3xx. // 8. Flicker is a feature, not a bug. Example output description (if rendered) A pulsating neon mandala — pink and cyan concentric rings warped by low-frequency analog noise. Scanlines shimmer vertically. The center hole oscillates like a breathing iris. Total register pressure: 4. Estimated fill rate: 2.1 Gpixel/s on embedded GPU. No discard , no sqrt except for radius. // boolean edge detection via fwidth (fast derivative)

// raw sinusoidal waves on axes vec2 q = p; q.x += sin(time * 1.7 + p.y * 8.0) * 0.1; q.y += cos(time * 1.3 + p.x * 7.0) * 0.1; No loops longer than 8 iterations
