   www.household.co.nz - the public site.

   The app's noticeboard, brought out onto the fridge door: paper, ink,
   pencil, a hairline rule, one highlighter stroke that marks exactly one
   thing, and red pen for the clash. The nine colours are the app's own
   (src/index.css, mobile/src/design/tokens.ts) - keep them in step.

   Static on purpose: no build, no script, nothing third-party.
