fix(docs): prevent mobile horizontal overflow

[jp-ayyappan]

Summary

• Clip the closed mobile navbar sidebar so the hide-on-scroll transition does not widen the page.
• Allow the Standards diagram grid to shrink to the viewport and stack footer links on screens narrower than 360 px.
• Import the platform OIDC guide and resolve links between imported pages locally; other relative platform document links point to their upstream source.

Bug report and visual evidence

Mobile screen recording in Slack

On a 390 px viewport, the page width grew to 714 px after the navbar hid. With the CSS fix applied, it stays at 390 px. The mobile menu still opens normally.

Validation

• git diff --check passed.
• Headless Chrome against the locally generated site: at 390 px, the navbar hid, page width remained 390 px, and the mobile menu opened.
• At 320 px, applying the grid and footer rules reduced page width from 353 px to 320 px.
• npm run build passed with Node 22 after the import fix. The generated Configuration and OIDC pages link to each other correctly.

Remote content maintenance

The import currently follows opentdf/platform main, so upstream edits can change this site's build without a docs commit. The link rewrite handles new relative Markdown links by sending unimported pages to their upstream source; external targets are not checked by Docusaurus. If upstream changes keep disrupting CI, pin this import to a reviewed commit or release and update that ref through a scheduled PR with a full site build.

Summary by CodeRabbit

• Style
  • Improved the standards section layout to better accommodate flexible content widths.
  • On screens narrower than 360px, footer links now appear in a single column instead of two.
  • On mobile screens, closed navigation menus no longer show horizontal overflow.

📝 Walkthrough

Walkthrough

The CSS changes adjust the standards grid sizing and mobile layouts for footer links and the closed navbar.

Changes

Responsive Layout Adjustments

Layer / File(s)	Summary
Standards grid sizing src/components/landing/Standards.module.css	The base grid column now uses minmax(0, 1fr). The diagram and content order rules add min-width: 0.
Mobile footer and navbar layout src/css/custom.css	At widths up to 359px, footer links use one column. At widths up to 996px, the closed navbar clips horizontal overflow; this rule does not apply while the sidebar is shown.

_{A rabbit checks the narrow grid,
And gives each column room to fit.
One footer column, neat and small,
The closed nav clips overflow from all.
The page sits tidy, wide or slight,
Then hops away into the night.}

Once the build passes, the preview will be at: https://opentdf-docs-pr-398.surge.sh

Common cause: If the build failed on vendored YAML validation, run the following locally and commit the result:
