References — bi-14-contribution

Primary sources first. In-tree Chromium docs beat any external source, including these modules.

• docs/contributing.md in your checkout — the authority.
• docs/cl_tips.md, docs/code_reviews.md, and the OWNERS documentation.
• issues.chromium.org — the live tracker.
• The Chromium blink-dev process for web-visible behaviour changes (intent-to-ship and friends).
• web-platform-tests contribution guide.

When a claim here proves stale, record it in PROGRESS.md section 7.
