References — bi-11-scheduling

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

• WHATWG HTML §Event loops, especially "update the rendering" and "perform a microtask checkpoint" — normative.
• platform/scheduler/README.md, TaskSchedulingInBlink.md.
• W3C Prioritized Task Scheduling (scheduler.postTask, scheduler.yield).
• Long Animation Frames API; Event Timing.
• React packages/scheduler/ — read after the lab, not before.

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