See [The Bananarchy Manifesto](./MANIFESTO.md) for the rationale behind this entire project.
Bananarchy targets the **Sxmo (`sxmo-de-sway`)** environment exclusively, tuned for 1:1 native `240x320` resolution, enlarged high-contrast typography, sub-115 MB idle RAM footprint on 512 MB devices, full Qualcomm QDSP6/Q6Voice audio and LTE modem routing, pre-integrated **Bantam** AI agent (`https://code.luxferre.top/luxferre/bantam-cpp`), a complete on-device development & scripting stack (`git`, `gcc`/`g++`, `make`, `nano`, `janet` + `jpm`, `perl` + `IO::Socket::SSL`, `tcl` + `tcllib`/`tcl-tls`/`sqlite-tcl`, `sqlite`), and a custom **6-mode `fcitx5-t9` input engine** supporting lowercase, one-shot Shift, Caps Lock, all 32 ASCII punctuation symbols, terminal control codes (`^A`-`^Z`, `Esc`, `Tab`, `F1`-`F12`), and direct numeric entry.
