// Global 5-second ticker used by relative-time helpers so their output
// renders as a live countdown. At this cadence the age column reads like
// a real-time clock for fresh transitions ("5s ago", "6s ago", ...) and
// the cost is a single reactive re-run per subscribed cell per second —
// no network, no DOM allocation, just string formatting. Identical-value
// updates (e.g. "2h ago" → "2h ago") are cheap because Solid's JSX
// compiler skips DOM writes when the new text matches the old.
//
// Reading tick() inside any reactive expression subscribes that
// expression to the ticker; when the interval fires, every subscriber
// re-runs. One timer drives the whole app.
