Steps Count Block Steps Count Block

A vaul bottom sheet wrapping a step-count chart. Each bar is a Base UI vertical slider whose fill is coloured by interpolating in OKLCH rather than sRGB, so the amber-to-green midpoint stays chromatic instead of collapsing to olive. The chart freezes its own scale for the duration of a drag so the bar tracks the finger exactly, then springs to the new ceiling on release. Days are added from a weekday-aligned calendar popover and removed from the header; the month select walks back twelve months. Every measurement is derived — the well's radius from the bars, the bar gap from how many days are on record, the sheet's radius from the card's.
