slider round 3: original thin rail, rimmed disc, ticks as true background

Owner refinements 2026-10-01:
- Bar back to the original h-1.5 rail (colors unchanged).
- Disc bleeds into its own fill no more: 2px #141414 rim on the thumb
  reads as a gap wherever it sits.
- Dashed stop ticks rebuilt as BACKGROUND LAYERS on the input itself:
  #141414 base color, four dashed tick gradients (30/50/70/90 only —
  the rail's ends already say 0 and 100) sized 1px x 100% at the
  thumb-center inset, and the fill gradient now TRANSPARENT past the
  thumb and painted on top — ticks live inside the bar, top to bottom,
  visible only on the empty side, never over the filled portion.
