PDR-007: Add SEO, Open Graph, Sitemap, and Structured Data Build Layer

[kas1987]

Objective

Make the ZELEX Concierge Atlas discoverable, shareable, and indexable by adding a proper metadata and static discovery layer.

Current state

The site has static HTML pages that hydrate catalog data from JSON. Basic titles exist, but product/character-level SEO, Open Graph, canonical URLs, sitemap, and JSON-LD are not yet implemented as a formal build output.

Scope

• Generate unique title and meta description per character/body/family/series page.
• Add Open Graph and Twitter card metadata.
• Generate sitemap.xml from catalog JSON.
• Add robots.txt and canonical URL strategy.
• Add JSON-LD for product-like character pages where appropriate.
• Add age-sensitive indexing policy notes.
• Add validation script or checklist for generated metadata.

Acceptance criteria

• sitemap.xml includes core pages and generated character/body URLs.
• Character pages have unique share metadata.
• SEO metadata can be regenerated from db/*.json.
• No explicit/private imagery paths are exposed incorrectly.
• Build docs explain how to validate output before launch.

Dependencies

• Existing Python build scripts
• db/characters.json, db/body_types.json, db/body_profiles.json
