Implementation plan

Change the YouTube tutorials button to blue

Steps

• In src/frontend/static/frontend/src/components/index/Homepage.tsx, update only the YouTube tutorials button's styling to use an existing blue style or color convention.
• Preserve the button's text, icon, link, and behavior, and make no changes to other buttons or global styles.

Acceptance checks

• Confirm the YouTube tutorials button is styled blue.
• Confirm its text, icon, link, and behavior are unchanged.
• Confirm the change is limited to src/frontend/static/frontend/src/components/index/Homepage.tsx.

Risks

• The repository's existing blue style convention is unknown; use the closest existing convention rather than introducing a new global style or inventing a color specification.

Implementation summary

Changed only the YouTube tutorials button from orange to the existing Semantic UI primary style in src/frontend/static/frontend/src/components/index/Homepage.tsx. Its text, icon, link, and behavior remain unchanged.

Validation executed by the runner

• Frontend TypeScript, lint and production build

Independent AI review (gpt-6-luna).

The change applies Semantic UI's primary button styling, which is blue by default. The link, text, icon, and other button attributes are unchanged, and the diff is limited to the requested file.

Human review is still required.
