+0.2.23 scope:
+- adds Appearance "Style depth" (`skin_depth`, V053): colors only / standard (default) / immersive
+- adds a separate "Style gradients" switch (`skin_gradients`, V053, default off); every stylesheet gradient is gated by it
+- interface-style standard: every predefined style ships light+dark palettes, a fixed layout profile and structural design tokens; 23 existing styles adapted, 14 new styles added (Dracula, Catppuccin, Solarized, Gruvbox, Tokyo Night, Rosé Pine, Everforest, Synthwave, Paper, Terminal, Aqua Glass, Linear, Material You, Retro 95)
+- V051/V052 consolidated into the fresh schemas; compatibility baseline V052
+- fresh MySQL schema: `message_loading_mode` uses an expression default
 
 0.2.22 scope:
 - adds message snooze (`snoozed_messages`, V052): hides a message client-side from its current folder view until a chosen wake time; purely client-side hiding, no server-side pagination/count SQL changes, no IMAP side effects
