Sill runs overnight sound and sleep assessments for the Norfolk trust. The interface is soft-UI, a style that usually extrudes everything and leaves patients guessing which parts respond. Here the extrusion is a grammar: raised means you can press it, pressed means it is reporting a number, and flat means neither. Three states, and a person can learn them in one night.
A raised block with a pressed slot cut into it: a sill with a window in it, and the whole grammar in one object. If a viewer only ever sees the mark, they have still been shown what raised and pressed mean here.
The mark, and the two reductions it is allowed
Seven elements: three you can press, three readings, one label. With the grammar on, three things look pressable and three of them are. Turn it off and the panel extrudes everything, which is what this style normally looks like.
The rule running · seven elements, three of them pressable
Soft-UI has a single surface colour by definition, so the palette is mostly not colour at all: it is a light and a dark that make the ground look like it has been pushed. The green does one job, which is marking the thing that is currently recording.
#E9ECF1#FFFFFF#C3CAD6#1F6F5CFour values · the green only ever means something is being measured
Manrope for everything spoken, DM Mono for everything measured. The split is the same as the shadow grammar: a number the clinic recorded is set in mono, and a sentence a person wrote is not.
Two sensors, no wires, one night
You can get up. The room keeps recording.
Everything on the bedside screen is written to be read by somebody half asleep who has never used it before and will not use it again. Short sentences, no jargon, and the one button that stops the session is always in the same place.

Two faces · mono means the clinic measured it
Five pieces. Two of them are paper, and paper has no shadows, so the grammar is translated rather than dropped: a keyline for what you can act on, a fill for what is being reported.
A clinic that measures and does not diagnose. Everything it says is either a number it recorded or an instruction it wants followed at 3am.
You slept six hours and twelve minutes. You woke four times, the longest for eighteen minutes.
You had a poor night’s sleep.
Press End when you get up. If you forget, we will stop it at seven.
Don’t forget to end your session!
Reported, not diagnosed. Your consultant sees this on Thursday.
Your results show signs of disturbed sleep.
You can get up. The room keeps recording.
Please remain in bed for accurate results.
This style has a reputation it earned, and every way it fails is a way of letting the shadow do a job the ink should be doing. Four, and the first ends it.
Sill is invented, built as a portfolio exercise in the neumorphism revival. Norwich and Norfolk are real; this clinic, its rooms, patients, reference numbers, readings and staff are not, and nothing here should be read as clinical guidance or as real sleep data. The approach is after the soft-UI look named by Michal Malewicz in 2019 and revived from about 2026, credited as an influence only. Part of the One Rule Each series.
Nothing is raised that cannot be pressed. Raised is a control, pressed is a reading, flat is neither, and there are two depths and no third.
