Summary

The design reference export script (export-design-reference.js) should support an optional --annotations=<dir> flag that loads field-level annotation YAML files and renders them as an "Annotations" tab in the ORCA design reference.

Details

• Load annotation YAML files that map fields to source (system, applicant, derived, etc.), program requirements, statutes, and notes
• Render a program requirement matrix with source badges and expandable statute/notes details
• The feature is fully opt-in — without the flag, behavior is unchanged

Also includes cleanup:

• Remove unused global state selector UI (sidebar buttons, CSS, JS)
• Update ORCA intro description to clarify the OOUX/ORCA methodology
• Default active tab to "attributes" instead of "overview"

Implementation is already done on prototype/harness (commit 01bb5ad) and needs to be cherry-picked onto its own branch.
