/* LifeNotes web · base: tokens, shell, sidebar (kept), topbar, auth, modal, toast.
   Tokens mirror the app's Aurora Borealis defaults (default ThemeMode.DARK, verified
   against ui/theme/Color.kt + Theme.kt): bg/toolbar #1A1B26 (one shared color, not two),
   card level 1 (surface) #21222D is a 3% lighten of it, card level 2 (surface-2) #282933
   is a 6% lighten, accent #BB9AF7. theme.js overrides the first five variables per
