File	Line	Rule	Text	Reason
dashboard/sso.mdx	138	WordList ("regex" → "regular expression")	"Matches regex" in Okta config table	This mirrors the Okta UI label. Changing it could make instructions inaccurate.

Methodology

Scanned all English .mdx files changed by 50 PRs merged between March 27 – April 2, 2026. Checked against all Vale warning-level rules (Ellipses, FirstPerson, HeadingPunctuation, Headings, OxfordComma, Ranges, Spelling, Will, WordList). Content inside code blocks, inline code, frontmatter, JSX components, and HTML tags was excluded per the Vale configuration.

Note

Low Risk
Low risk documentation-only edits (heading capitalization and minor wording) with no behavioral or configuration changes.

Overview
Resolves Vale/style warnings across a few MDX docs by adjusting heading sentence case (e.g., FAQ and troubleshooting, Iframes) and tightening phrasing to avoid future tense.

Also clarifies wording in create/changelogs.mdx around page modes hiding navigation elements and how RSS entries exclude non-Markdown content.
