   v5.14 · same font stack as app.css (the browser's sans-serif, no font downloads), the site's blue,
   ink and line colours, 8px / 14px radii, compact spacing so the register page fits a laptop screen
   without scrolling. 5.14: the submit button keeps its place and shows the spinner inside itself
   (no jump), remember-me row, dimmer placeholders, a little more air on short screens and phones.
