   Little Plot Works — visual system
   PLOT     corner stakes frame the working surfaces (never a generic card)
   MEASURE  dimension lines with slash ticks, always in surveyor's red
   PLACE    numbered pins annotate steps, on the homepage and in the tools
   GROW     a plant is a centre mark inside its dashed spacing zone
   Type: Familjen Grotesk (display + big numbers), Atkinson Hyperlegible Next
   (reading + UI), Atkinson Hyperlegible Mono (dimensions and units only).
   Colour is state: ink = structure & action, green = fits/placed,
   red = measured, amber = needs attention.
   Breakpoints: 1080 · 900 (workbench stacks) · 700 (mobile) · 420 · 340
