 - **I/O**: Use `StreamUtils::WriteBufferingStream` for buffered writes.
 - **Validation**: Run schema hooks on create/update; on failure revert and return a validation error.
 - **Naming**: lowerCamelCase for methods/vars, UpperCamelCase for types, ALL_CAPS for simple constants/enums.
-- **Formatting**: Use a consistent `clang-format` (LLVM/Google); keep lines ≤ 120 cols.
+- **Formatting**: Follow the repository `.clang-format` + `.editorconfig` baseline from `esptoolkit-template` (LLVM-derived style, `ColumnLimit: 100`, tabs with width `4`, `BinPackArguments/Parameters: false`, `AllowShortFunctionsOnASingleLine: None`).
 - **Allocations**: Avoid hidden allocations in hot paths and inside event callbacks & sync loops.
 
-Optional `.clang-format` starter (Google-like):
-```yaml
-BasedOnStyle: Google
-IndentWidth: 4
-ColumnLimit: 120
-DerivePointerAlignment: false
-PointerAlignment: Left
-AllowShortFunctionsOnASingleLine: Empty

+## Formatting Baseline
+
+This repository follows the firmware formatting baseline from `esptoolkit-template`:
+- `.clang-format` is the source of truth for C/C++/INO layout.
+- `.editorconfig` enforces tabs (`tab_width = 4`), LF endings, and final newline.
+- Format all tracked firmware sources with `bash scripts/format_cpp.sh`.
