## WSG Modularization Analysis

- WSG reference: Modularize bandwidth-heavy components (https://www.w3.org/TR/web-sustainability-guidelines/#modularize-bandwidth-heavy-components)
- Modularization score: 0 (few obvious on-demand opportunities) to 100 (many heavy initial-load components)
- This analysis looks for heavy scripts, images, styles, fonts, and media that should be split or loaded on demand.

## Cross-Page Patterns

- This same heavy image pattern appears on 99 pages. Fix it once in the shared template, CMS block, or design system component to reduce load across the whole site.
- These 1 script bundles are recurring modularization targets. Move the fix to the shared bundle or component boundary so every affected page gets lighter at once.
- These 3 modularization targets recur across multiple pages. Centralize the fix at the component or bundle level instead of treating each page separately.
- Heavy assets from administracion.gob.es recur across 100 pages. Review whether that dependency should be deferred, optimized, or loaded conditionally.

### Recurring Heavy Assets
