   ----------------------------------------------------------------------------
   ΟΛΕΣ οι σελίδες (επεκτείνουν base.html / auth_layout.html) αποκτούν αυτόματα
   iOS-like εμπειρία σε mobile & tablet:
     · off-canvas drawer sidebar + frosted bottom tab bar
     · safe-area insets (notch / home indicator)
     · momentum scrolling, tactile :active feedback, χωρίς tap highlight
     · adaptive πίνακες (momentum horizontal scroll + auto-card σε phones)
     · bottom-sheet modals
   Όλα είναι ΑΥΣΤΗΡΑ scoped σε mobile/tablet breakpoints (<1024px).
   Το desktop (≥1024px) ΔΕΝ επηρεάζεται καθόλου.
