- Use pipelineStore.globalConfig instead of DEFAULT_PIPELINE_CONFIG for image processing, so global preset changes affect images - Fix preset saving from modal to save actual edited config, not global - Add local preset selection tracking in PipelinePanel for modal context - Prevent modal config reset when store changes using untrack() - Derive editingImage from store to always get latest data - Fix ImagePreview to compare against lastProcessedConfig, not initial - Preserve custom image overrides when global preset changes - Clean up unused store functions (updateConfig, updateStep, isModified, getEffectiveConfig) - Use clonePipelineConfig consistently instead of JSON.parse/stringify Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
