Future Enhancements (Post-Phase 9)

Context Preservation

Key Architectural Decisions:

  • Same three-layer CSS system as theme editor
  • LoadTheme plug provides @theme_settings and @generated_css assigns
  • CSS cached in ETS via CSSCache GenServer
  • Preview data used until real Products context exists
  • Shared components in components/shop/ directory

Critical Files:

  • Theme editor: lib/simpleshop_theme_web/live/theme_live/index.ex
  • CSS generator: lib/simpleshop_theme/theme/css_generator.ex
  • Settings context: lib/simpleshop_theme/settings.ex
  • Preview data: lib/simpleshop_theme/theme/preview_data.ex

Current State (as of last update):

  • Theme editor fully functional at /admin/theme
  • 8 presets working with real-time preview
  • All customization options implemented
  • Logo/header uploads with BLOB storage working
  • SVG recoloring functional
