The presentation player grew up for its viewers

Two weeks after Phlo Presentation could make a film, attention moved from the editor to the person watching it. The player gained the things a video on somebody else's page actually needs.

Multi-instance boot came first. The player used to expect one presentation per page, which is fine for a play page and wrong for a homepage with a film in the middle of it. Now boot() wires up every .pp-embed on the page, a MutationObserver restarts the idempotent boot after an SPA swap, and data-lang lets the hosting site decide which language the film speaks. That last one matters more than it sounds: on this site the film follows the site language, so a Dutch visitor gets the Dutch audio without touching a control.

Then lazy media. An embed used to fetch its video and audio on load, which means a page carrying a film pays for it whether or not anyone presses play. Now it costs its poster images until the first play. A poster moment is a chosen point on the timeline, so the still is a frame you picked rather than whatever frame zero happens to be.

Smaller pieces, all from watching people use it: volume and mute remembered in local storage, position kept in session storage so a language switch does not restart the film, controls that hide themselves during playback, and an accessible surface with aria labels that follow the state.
