• The seek bar is the tape path between two reels. As you watch, the left reel thins and the right one fills, so you read progress before you read the time. The reels turn while the video plays and spin faster when you scrub.
• Transport keys travel down when pressed, and Play stays down while the tape runs, like a real deck.
• Time lives in a monospaced tape counter. The title is a paper label with a Side A tab.
• Volume is a mixer fader, and settings open like a J-card above the deck, so they never cover the tape.
