fix(web): restore clickable controls on non-English routes

[Hmbown]

Report

Clickable controls on the localized, non-English website routes are not working reliably. The exact affected locales and controls still need a current-browser matrix, but this is visible outside the English route and should be treated as a localized interaction bug rather than copy-only polish.

Audit scope

• Navigation links and icon buttons
• Mobile menu and locale switcher
• CTA cards and buttons
• Copy-to-clipboard controls
• Any locale-specific overlay or translated markup that can intercept pointer/keyboard input

Acceptance criteria

• Reproduce and record the broken control(s), route(s), viewport, and browser before changing code.
• Fix pointer and keyboard activation without weakening semantics or focus visibility.
• Verify at least one CJK locale and one non-English Latin-script locale on desktop and mobile viewports.
• Confirm English behavior does not regress.
• Add interaction-level regression coverage for the underlying failure, not only snapshot/copy assertions.
• Attach browser evidence and note any remaining locale-specific gaps.
