[#114] Fix footer copyright text WCAG AA contrast

[realproject7]

Summary

• Changed footer copyright text-[10px] to text-xs (12px) for minimum readable size
• Removed /60 opacity modifier from text-muted/60 to improve contrast ratio to WCAG AA compliance

Fixes #114

Test plan

• Verify footer copyright text is visually larger (12px vs 10px)
• Run contrast checker on text-muted against dark background (#0a0a0a) — should pass WCAG AA (4.5:1)
• Confirm no layout shift from the size change

Verdict: APPROVE

Summary

The PR makes the exact footer contrast fix requested in issue #114 with a minimal single-line change in Footer.tsx. The updated size and color class remove the obvious WCAG AA risk called out in the issue.

Findings

• None.

Decision

Approve because the implementation matches the acceptance criteria, stays narrowly scoped, and the lint-and-typecheck check passed.

T2b Review: REQUEST CHANGES

The direction is correct (removing opacity + increasing font size), but the result still doesn't meet WCAG AA for normal text:

• text-muted resolves to #737373 on #0a0a0a background → 4.18:1 contrast ratio
• WCAG AA requires 4.5:1 for normal text (12px / text-xs is not large text)

Suggested fix (pick one):

1. Bump --text-muted in globals.css from #737373 to #7a7a7a or higher (passes 4.5:1 globally)
2. Use a one-off lighter color on this element (e.g. text-neutral-400 or similar that yields ≥4.5:1)
3. Increase to text-sm (14px) — still normal text though, so color fix is the real solution

T2b Re-review: APPROVE

text-neutral-400 (#a3a3a3) on #0a0a0a yields ~6.3:1 contrast — comfortably passes WCAG AA (4.5:1). Good fix.

Verdict: REQUEST CHANGES

Summary

The font-size increase is correct, but the footer text still does not meet WCAG AA contrast after this PR. text-muted resolves to #737373 in src/app/globals.css, and against the existing #0a0a0a background that is only 4.18:1, still below the required 4.5:1 for normal text.

Findings

• [medium] Footer contrast is still below WCAG AA after this change
  • File: src/components/Footer.tsx:28
  • Suggestion: Use a lighter compliant color for this element, or raise --text-muted in src/app/globals.css to at least #7a7a7a so the footer text actually clears 4.5:1.

Decision

Request changes because the current patch does not fully satisfy issue #114's accessibility requirement.
