Server: ThemeConfig entity + CRUD (GET/PUT /theme), SQLite persistence, ThemeUpdate broadcast to ESP32 on save and initial connect. Client: render engine uses theme colors, full-screen redraw on theme change. SPA: theme page with color pickers + presets, layout preview with TS port of layout engine, justify/align controls on containers. DisplayHint refactored to struct (kind + h_align + v_align).
