From 7185005f9bc9a62d44f40219643b2262b9b261af Mon Sep 17 00:00:00 2001 From: David Gwilliam Date: Sat, 21 Mar 2026 13:09:37 -0700 Subject: [PATCH] feat(figment): complete pipeline integration with native effect plugin - Add engine/effects/plugins/figment.py (native pipeline implementation) - Add engine/figment_render.py, engine/figment_trigger.py, engine/themes.py - Add 3 SVG assets in figments/ (Mexican/Aztec motif) - Add engine/display/backends/animation_report.py for debugging - Add engine/pipeline/adapters/frame_capture.py for frame capture - Add test-figment preset to presets.toml - Add cairosvg optional dependency to pyproject.toml - Update EffectPluginStage to support is_overlay attribute (for overlay effects) - Add comprehensive tests: test_figment_effect.py, test_figment_pipeline.py, test_figment_render.py - Remove obsolete test_ui_simple.py - Update TODO.md with test cleanup plan - Refactor test_adapters.py to use real components instead of mocks This completes the figment SVG overlay feature integration using the modern pipeline architecture, avoiding legacy effects_plugins.
