From b9c2a0394343ff3586880d118b7d549b3e748cad Mon Sep 17 00:00:00 2001 From: skal Date: Sat, 28 Feb 2026 11:50:13 +0100 Subject: refactor(effects): co-locate effect WGSL shaders with their .h/.cc in src/effects/ Move 13 effect-specific shaders from workspaces/main/shaders/ to src/effects/ so each effect's .h, .cc, and .wgsl are together. Update assets.txt paths in both main and test workspaces. Update EFFECT_WORKFLOW.md to reflect new location. Shared/reusable snippets remain in src/shaders/. handoff(Gemini): shaders moved; src/effects/ now has .h, .cc, and .wgsl per effect.
