 /**
  * Lays the content out at [contentWidth] and then draws it shrunk to the width the parent offers,
  * reporting the scaled-down size so the surrounding layout still measures correctly.
  *
  * This is what makes a thumbnail of a real screen component possible: a widget rendered directly
  * into a 150dp tile is not the same widget the dashboard shows — its text wraps, its rows collapse,
  * its hero typography overflows. Measuring at the dashboard's own width and scaling the result
  * keeps the proportions the user is choosing between.
  *
  * Scale is capped at 1: a tile wider than [contentWidth] shows the component at its natural size
  * rather than magnifying it into a blur.
