[Docs] Document sections and customization patterns

[hta218]

Context

Naturélle should be easy to customize in Weaverse Studio. Merchants and implementers need docs explaining when and how to use each section.

Goal

Document Naturélle's sections, recommended usage patterns, and page composition examples.

Scope

Document:

• Available sections and blocks
• What each section is for
• Required/optional settings
• Recommended image sizes and aspect ratios
• Recommended content/copy patterns
• Mobile behavior notes
• Homepage composition examples
• Collection/PDP/editorial page composition examples
• Common mistakes to avoid

Deliverables

• docs/sections.md or equivalent
• Section usage table
• Example page structures
• Screenshots if useful

Acceptance criteria

• All key Naturélle sections are documented.
• Each section has purpose, settings, image/content guidance, and usage notes.
• Example page compositions are included.
• Docs are clear enough for a non-core developer to use.
