Detailed Description

ESP32-C2 (ESP8684) die profile - single RISC-V, 272 KB SRAM, Wi-Fi 4 + BLE 5.0, no PSRAM.

The cheapest/smallest die: 272 KB SRAM is tighter than the classic ESP32's usable DRAM, so it stays at the conservative floor (no sizing bump). Reduced crypto: SHA + ECC only - there is NO general-purpose AES peripheral (AES exists only as the XTS flash-encryption engine) and NO RSA/MPI, HMAC or DS, so secure boot is ECC-based. Do not assume "any ESP32 has AES/RSA". No PSRAM. classic_defaults.h is pulled in last as the sizing floor; every macro is #ifndef-guarded.
