- Nou format de pack AE26 v1 (XOR + djb2), eina `pack_resources`, regeneració automàtica de `build/resources.pack` a cada build. - `Resource::Helper` amb init/shutdown, fallback a disc només en Debug (apunta al source tree); Release exigeix pack present. - Callers de YAML migrats a `loadFile`+deserialize des de buffer. - Arrel neta: el pack viu a `build/`, eliminat `sync_data`. - Placeholder font -> `ari-w9500-condensed-display`; esborrades variants bold/condensed no usades a `data/fonts/`.
