From 95802739b8ccaf9112fe4fe6e496ba7ae4158aae Mon Sep 17 00:00:00 2001 From: skal Date: Fri, 6 Mar 2026 22:53:29 +0100 Subject: feat(effects): add Scratch post-process effect with reusable scratch_lines snippet - src/shaders/render/scratch_lines.wgsl: reusable WGSL snippet registered as "render/scratch_lines"; call scratch_lines(uv, resolution, time)->f32 from any effect. Uses hash_1f from math/noise; 8 lines/frame, ~24fps flicker. - src/effects/scratch.{wgsl,h,cc}: thin Scratch effect wrapping the snippet. - Applied to "intro" and "rotating_cube" sequences as the final step. - 35/35 tests passing. handoff(Gemini): Scratch effect added. render/scratch_lines snippet is reusable.
