The route-smoke deploy guard grepped the live bundle for MaintenanceMode's
strings ("Coming Back Soon" / "maintenance_home") to detect a maintenance-on
build. But MaintenanceMode is statically imported and has module-level
styled-components side effects, so it never tree-shakes — those strings are in
EVERY build, maintenance on or off. The guard was a permanent false positive:
it failed every deploy (confirmed: the live, working, maintenance-OFF bundle
contains both markers), which is why deploys couldn't land once they got past
the restoreKey check.
Emit a dedicated sentinel from App.tsx inside `if (VITE_MAINTENANCE_MODE ===
'true')`. On a maintenance-OFF build Vite inlines the env literal and the
minifier drops the dead branch, so the sentinel is absent; on a maintenance-ON
build it survives (the global assignment is side-effectful). route-smoke.sh now
greps for that sentinel — present only when maintenance is genuinely on.
