/* Developer-mode strip — sits flush at the very top of the viewport above
   the topbar when CFG_DEV_MODE is on. Above-chrome is the standard env-
   banner placement (Stripe test-mode, GitHub staff-mode); pushing the
   topbar down 36px is a deliberate signal that the environment is non-
   standard. Neutral glass so it reads as "system bar" not "warning"; only
   the icon picks up the theme accent. Body gets .has-dev-banner to bump
   padding-top + shift every other fixed-positioned chrome element down
   by the strip's height. Dismissal is local and remembered in
   localStorage until dev mode is toggled off + on again. */
