Parameter Registry

Parameter definitions come from proto/params_schema.json — the single source of truth for both client and server. Schema version: 1.0.0.

Each language references parameter keys via compile-time constants (e.g. TI_PARAM_PRINT_SPEED_TIMER), combined with typed helper functions (set_int / get_int / set_bool / …).
