The stale screen problem: offline-first signage that fails loudly
A dark screen is a support ticket. A screen still showing last week's price is a lie in your store, and nothing in a normal monitoring stack will tell you about it. Content as a versioned bundle instead of a URL, day-parts that depend on a clock you don't control, expiry as a safety feature, and telemetry that reports what's actually on the glass.
