  <div class="note">
    <strong>3 DaisyUI-v5 regressions were caught in review and fixed</strong> (form alignment, tab styling, theme-dropdown clipping) — see the dedicated section below. <br><br>
    <strong>⚠ One intentional visual change remains (not a regression):</strong> DaisyUI&nbsp;v5 ships a refreshed default-theme palette — the <code>primary</code> button color shifted from v4's indigo/violet to a brighter blue, and <code>badge-success</code> green is slightly more saturated. All components render correctly and cohesively; this is the theme-token evolution the spec's edge cases anticipated. If exact color parity is required, the old palette can be pinned via a custom <code>@plugin "daisyui/theme"</code> block — flagged here for a product decision.
  </div>

  <h2>Visual Parity — Before / After ({len(stems)} views)</h2>
  {''.join(pairs_html)}

  {qa_html}

  <h2>Verdict</h2>
  <p>The four major upgrades build clean on Node&nbsp;24, embed into both the personal and server Go editions, and pass the full Vitest suite. A 9-view Playwright sweep plus QA use-case scripts confirm the UI renders and behaves on par with the pre-migration build, with the single documented DaisyUI-v5 palette refresh. <strong>Ready to ship.</strong></p>
