/* ─────────────────────────────────────────────────────────────────────────────
   Shared application shell — the side panel, the wallpaper and the dark
   palette that the onboarding form, the submissions inbox and the /old
   dashboard all draw from.

   Three surfaces were built separately and looked it. This file is the one
   place their common chrome lives, so a change to the panel or the palette
   lands on all of them at once. Everything here is prefixed `le-` because two
   of those surfaces already own generic class names like `.mesh` and `.card`.

   Loaded from the site root as /shell.css by the two static pages, and
   imported directly by the React app.
