After clearing the page-texture cache, the worker's first drawSpread had to load the EB
Garamond faces AND rasterize inside a single 4s draw-timeout budget. On a cold load that could
exceed 4s, so the timeout fired, the draw resolved to null (no title painted), the loader then
completed over a black scene, and the title only appeared on a later render ("the image
returned outside the loader's progress indicators").
The renderer now awaits the worker's fonts-ready signal before its first timed draw (with a
15s safety cap so it can't hang), so font loading happens during the loader as its own step
rather than inside a draw's timeout window. Draw timeout raised 4s -> 6s for cold-render
headroom. Verified live: title page renders within the loader, no texture-worker-timeout
problems. Suite 178.
