/* ---------------------------------------------------------------------------
   Login screen.

   Follows the split-screen pattern from the chemavi.cm reference: a branded
   panel on the left carrying the promise, the form on the right carrying the
   work. Written from scratch against our own palette rather than copied — the
   reference ships a 53 KB stylesheet for four auth screens, and we have one.

   Palette is the site's: near-black ground, lime accent (see core/styles/style.css).
