v0.1.6

Changed

• Theme tokens: two colours for navigation labels (--color-text-nav,
  --color-text-nav-active). Every module carries the same token sheet, so the
  values must match across them — whichever bundle loads last would otherwise
  win. No visible change inside this module.
• The search bar follows the new default background (#e9eef6).
• Default application background token aligned with the core (--body-bg #f8fafd). Only
  visible when the module runs standalone: inside the shell the active theme sets it.
• Search bar background now comes from the --color-search-bg token (unified at #e9eef6)
  rather than a hard-coded colour.
