On a near-black stage sits a low anodised chassis with four round sockets on its deck and a strip of black glass in its face. Four glass valves hang above the sockets, each with a grey metal plate inside that has a symbol cut through it: a calendar, a shopping bag, lines of text and an envelope. Press a valve and it drops into its socket. The cut-out symbol stutters up to a blue-white glow the way a heater comes to temperature, light blooms around the glass and spills down the front of the chassis, and one cell of the display wakes up. The display is a small fluorescent drawing of a surf school's home page, with unlit parts left faintly visible. Press a seated valve and it lifts out, tilts and goes cold. Without input the piece seats all four, then pulls and replaces one at a time. It is drawn 520 pixels wide and scaled as one object on phones.

No. Each valve is a rounded element with an inset outline, two vertical highlight streaks, a soft band on the far side and a silver gradient in the crown for the getter flash. The glow is three radial gradients: one inside the bottle, one around it and one on the socket.
The symbol is drawn twice in the same place. The lower copy is nearly black, like a hole cut in the plate. The upper copy is pale blue with two drop shadows, and only its opacity is animated.
Every cell renders its drawing once at 13 percent opacity and once at full brightness inside the glow wrapper. Real fluorescent displays show their cold segments faintly, and keeping them makes the lit state read as light and not as content appearing.
`seated` is an array of four booleans in the root component. Initialise it from your own data and call your save function inside `toggle`, where the state is already being updated.
Only the highlight streaks on the glass. The root writes the pointer's horizontal position into a CSS variable and the streaks shift up to seven pixels, which is enough to make the glass feel curved.
