Navigation Timing

Tells a reload from a link, so a reload never autoplays.

A post with its tracks listed, and the player bar along the bottom of the screen — Arriving here from a link resumes the music; a reload shows the bar paused at the same spot.

How Riff uses it

When restoring the saved state, the script reads the type of the navigation entry. After a reload the saved track loads at its position but stays paused. After a link, a track that was playing resumes.

Why

The click that follows a link is the gesture the new page needs to play with sound. A reload has no such gesture and would be blocked or surprise the listener.

Without it

The entry is optionally chained, so without one the saved playing flag decides alone.
