# Build the patched headless_shell (pixelshot turbo capture path) and attach it
# to a `chrome-<version>` release. Manually triggered.
#
# NOTE: a full Chromium build needs ~100 GB disk and 1-2 h. GitHub-hosted runners
# cannot fit it, so this targets SELF-HOSTED runners that have depot_tools, a
# Chromium checkout, and the platform toolchain. Label your runners with
# `chromium-build` plus the OS. macOS binaries must be codesigned/notarized
# (add the signing step for your Apple account). See render/chrome-build/BUILD.md.
