/* ============================================================
   DIGIX AI v4 — home.css
   Styles for both Home states:
   - Disconnected: command-grid / hc-panel / flow / security-list
     (unchanged from the original build).
   - Connected: masthead / deck / card (Glass Deck).
   Uses the app's existing color variables throughout (defined in
   styles.css) rather than introducing new ones, so nothing here
   shifts the palette anywhere else in the app.
   ============================================================ */

/* ---------- shared: disconnected-state layout ----------
   Desktop: boot + flow stacked in the left column, login card
   filling the right column (spans both rows).
   Mobile: single column, ordered boot -> login -> flow, so the
   login card isn't buried below the connect-flow steps. */
