PatternFly Guideline: https://www.patternfly.org/v4/ux-writing/capitalization

Similar to PatternFly, sentence case is the standard across Red Hat products. However, capitalization will vary depending on each product area's context. In general, follow these guidelines:

• Write navigation items and their corresponding page titles in title case.
• Write all other areas (like menu items, button text, form field labels, and empty state headings) in sentence case.
• Capitalize proper nouns, acronyms, initialisms, product names, services, and features.

Capitalize Red Hat feature names when they’re used as proper nouns or when they refer to a capitalized UI term (like a navigation item). Write them in lowercase when they’re used to describe generic concepts.

1. Navigation: Navigation items are in title case.
2. Menu: Menu items are in sentence case.

Capitalization Types

Title case capitalizes only the first letter of each word in a sentence except for smaller words like articles and conjunctions that have fewer than four letters.

Sentence case only capitalizes the first letter of the first word in a title, heading, subtitle, or subheading except for proper nouns, product names, acronyms, and initialisms.
