Capitalized Translation Values
For locales whose writing system supports capitalization, begin every translation entry value with a capital letter. Apply this to the first letter of the displayed text, including values used as labels, messages, and sentences. Locales without capitalization are not subject to this rule.

{ "welcome": "welcome" }

Capitalize the first letter of each affected translation value without changing its translation key or meaning.
