- Run webhint in parallel with other site checks, right after the
deployment finishes
- Fix webhint perf budget (it warns when within 0.5 sec so give it a
0.5 sec buffer)
- Throttle LH a bit more
- Replace achecker flags with a config file
- Bring back webhint
- Amend check-whole-site so that it will deploy to staging if all checks
pass, and then run webhint on every staging page.
