/* Factory house style, version 1.
   One stylesheet shared by every app the factory builds, so they look like
   one family. It styles plain HTML elements directly: a page that uses
   <header>, <main>, <h1>, <form>, <label>, <input>, <button>, <table> and
   <footer> looks right without any class names. Works on phones and desktops,
   in light and dark mode. No fonts, images or anything else from the internet.
   Agents: copy this file unchanged to static/house-style.css. Put anything
   special to one app in a separate static/app.css, loaded after this one. */
