Replace all fixed strings in the project with t() strings.
common vs translations
Generic texts like "Apply", "Click here", "Download", .... can go to common.json.
Texts more specific to the Catalog project should go to translations.json.
Feel free to ask for advice.
ui/common Components
All components need to be exported as translate()(...).
Translations here should go to common.json. Start with these, please.
src/xxxx modules
These go to translations.json.
Please use {moduleName}.xxxx as keys.
