-| **C / C++ on ESP-IDF**          | Reference platform, every peripheral has a driver, fastest path to first pixel.                                                                                          | Refactoring at scale is painful; memory safety is on you.                                                                       |
+| **C on ESP-IDF (no Arduino)**   | Reference platform on the bare native SDK; every peripheral has a driver; smallest binary of the C-family options; no C++ runtime / exceptions / RTTI to reason about.   | All memory safety on you; no RAII for resource cleanup; no generics so widget / state code gets repetitive; refactoring at scale is painful. |
+| **C++ on ESP-IDF**              | Same peripheral coverage as C; RAII, templates, and `std::` containers ease widget / state code; mature in the ESP-IDF examples.                                         | Exception / RTTI story on embedded is messy; ABI / linker surprises; memory safety still on you; binary larger than plain C.    |
 | **Rust on `esp-idf-rs` (std)**  | First-class Espressif-sponsored Rust support; `std` gives heap / threads / VFS / mbedtls; can use the broader Rust ecosystem (`gitoxide`, `ropey`, `embedded-graphics`). | Larger binary than `no_std`; longer build times; some `unsafe` at FFI seams.                                                    |
 | **Rust on `esp-hal` (no_std)**  | Smallest binary, most "pure" embedded experience.                                                                                                                        | No `std` = no off-the-shelf git, no easy TLS, would re-implement a lot of plumbing.                                             |
 | **Gleam + Shore on AtomVM**     | Beautiful language, the user's stated preference.                                                                                                                        | BEAM on ESP32 is memory-hungry; no bindings for USB host, e-ink, SD, TLS, git in that ecosystem. Two research projects stacked. |
