/* ============================================================================
   Quick Start — the first-login onboarding guide
   ----------------------------------------------------------------------------
   A full-screen overlay (not the shared #modalRoot card) for one reason: the
   steps CONTAIN the app's own workflows (the account modal, the composer), and a
   small centred card would leave the user squinting at a dialog behind a dialog.
   Full-bleed also gives the mobile layout the thing it actually needs — a sheet
   whose primary button sits under the thumb.

   STACKING ORDER is part of the contract:
     64  .mobile-bottom-nav
     72  .ob-veil            <- this file
     80  #modalRoot          <- the real "Add account" modal opens ABOVE the tour
     90+ toasts
   The tour must sit UNDER #modalRoot, or tapping "Connect Telegram" would open
   the connection form behind the overlay that asked for it.

   Every horizontal rule here uses LOGICAL properties (inline-start/end) so the
   Farsi/RTL build mirrors without a second stylesheet.
