Browser automation

Two pathways — never mix in the same spool dispatch.

exec:browser runs JS against page. Globals available: page, snapshot, screenshotWithAccessibilityLabels, state. 15s live window, then backgrounds; output drains automatically on every subsequent plugkit call.

browser: prefix is playwriter session management. One command per block.

Core

Write to .gm/exec-spool/in/browser/<N>.txt:

await page.goto('https://example.com')
await snapshot({ page })
