[WEB-04] Add accessibility, performance, SEO, analytics privacy, and release checks

[jaavid]

Background

CoreLink is managed as one product across multiple implementation boundaries. This work is owned by website under EPIC-08.

Problem

The organization does not yet have verified, consistently maintained evidence for this outcome: Add accessibility, performance, SEO, analytics privacy, and release checks.

Goal

Add accessibility, performance, SEO, analytics privacy, and release checks and make the result the authoritative, reviewable baseline for all affected repositories.

Parent

• Primary Product Epic: EPIC-08
• Backlog ID: WEB-04

Scope

• Deliver the stated outcome in website.
• Reconcile affected organization policy, product claims, ownership, security, release, documentation and repository maturity.
• Retain acceptance evidence for the Beta gate.

Out of Scope

• Runtime feature implementation in this Issue.
• Duplicating the product roadmap in repository README files.
• Presenting scaffolds or planned capability as a supported release.

Acceptance Criteria

• The outcome is documented or configured in its authoritative location.
• Affected repositories link to the source of truth instead of copying it.
• Ownership, review and exception paths are explicit.
• Security, license, privacy and release impacts are addressed where applicable.
• The result is validated against at least one real repository workflow.
• Acceptance evidence is linked and the parent Epic is updated.

Technical Notes

Use organization-wide defaults where inheritance is reliable. Repository-specific exceptions must be minimal and documented. Product maturity claims must distinguish Scaffold, Experimental, Alpha, Beta, Stable and Deprecated.

Dependencies

• Blocked by: WEB-01
• Blocks: Resolved during refinement.
• Cross-repository: Link concrete affected Issues; do not duplicate implementation.
