Identify repeated patterns and merchant-managed decisions before deciding which components need settings or reusable snippets.
Keep Liquid queries bounded, use responsive images, avoid duplicated JavaScript and document unusual dependencies near the owning code.

Separate content decisions from implementation details
Identify what merchants need to change regularly: a campaign image, product explanation, featured collection or call to action. Give those decisions clear settings. Avoid exposing every spacing value or internal option when the result is an editor that requires knowledge of CSS to use safely.
Choose a clear owner for each reusable pattern
Use sections for merchant-composed page areas and snippets for focused repeated markup or behaviour within the theme’s architecture. Keep parameters explicit so the same card does not depend on a hidden page-specific variable. Reuse should reduce inconsistency without forcing genuinely different content into a generic block.
Keep assets proportional to the page
Inspect which styles and scripts a template requires and avoid loading a large feature everywhere for one section. Use responsive image output and reserve media dimensions. Check that dynamic section rendering does not attach duplicate listeners or leave components uninitialized after the editor changes the page.
Document the exceptions worth preserving
Record unusual app dependencies, product-data assumptions and reasons for custom behaviour near the relevant implementation. Provide merchant instructions for the supported layouts. Future work becomes easier when a developer can distinguish an intentional business rule from an accidental workaround before changing it.
Checks for this implementation
- Review repeated markup and scripts for a clear owning component.
- Test settings with empty content and long realistic text.
- Keep template and theme-editor behaviour aligned after section changes.
Common mistake to avoid
Turning every small visual property into a setting can make the editor harder to use and the code harder to reason about.
Good architecture reduces regression risk and lets future work focus on customer value instead of untangling templates.
