/*
  Renovation Materials Calculator landing.
  The site is a drawing sheet: birch-plywood ground with drafting crosses, walnut walls, and the pink
  of a chalk line for everything that has been measured. The feature section is a floor plan whose
  rooms hold the app screens; the footer is the title block of the sheet.
  Colours and type are the app's own (plywood, sheet, veneer, walnut, chalk pink; Chakra Petch for
  titles and every number, Hanken Grotesk for text).
