Summary

src/pages/volunteer.astro:136 sets frameborder="0" on an <iframe>. The frameborder attribute has been deprecated for years — modern HTML spec says use CSS border: 0 instead (which is the default for iframes anyway in modern browsers).

astro check warning

src/pages/volunteer.astro:136:9 - warning ts(6385): 'frameborder' is deprecated.

136         frameborder="0"
            ~~~~~~~~~~~

Suggested fix

Delete the frameborder="0" line. If the iframe shows a visible border in some browser, add style="border: 0" or a CSS class instead.

Acceptance criteria

• Warning clears.
• Volunteer page iframe still displays without a visible border in major browsers.
