error saving style config file: %v

Error message

error saving style config file: %v

What it means

Raised in GetStyleConfig when os.WriteFile cannot persist the freshly marshalled default style config to PRODUCT_CONFIG_PATH/<domain>/style_config.json (the file did not exist and the code attempts to seed it). Failure means the domain config directory is missing, permissions are wrong, or the disk is full.

Solutions

1. Create PRODUCT_CONFIG_PATH/<domain>/ with appropriate permissions before first style access
2. Grant the service user write access to the config tree
3. Free disk space if the volume is full
4. If writing defaults is optional for the caller, degrade gracefully by returning the in-memory default instead of failing
