/* Household Finance — minimal theme (v5): flat, square, quiet.
   No gradients, glows, shadows, blur or texture. Hairlines instead of tiles. 2px corners. One restrained accent.
   Type: the phone's own UI font (no outside fonts: the security policy blocks them), tabular numerals for money.
   Dark is the default; light is html[data-theme="light"] (Appearance in More).
   Buttons: .btn = primary (one per screen, solid) · .btn.alt = secondary (outline) · .ghost = small utility ·
            .chip = filter · .seg = switch · .tabs = navigation · .addbtn = the one creation action (centre of the tab bar). */
