/* ==========================================================================
   Lockout — landing page
   --------------------------------------------------------------------------
   The palette and the type are lifted from the app itself (ios/HabitLockout/
   Theme.swift), not invented for the web. That file's rule about colour is
   worth repeating here because the whole page depends on it:

     violet = action.  mint = progress and the clean state.  red = consequence.

   Red is spent in exactly three places on this page — the slip card, the
   countdown, and the step-02 numeral. If red is everywhere, red means nothing.
