Greptile Summary

• Adds mobile-responsive behaviour to the paused project modal: on small viewports (≤767px), the Upgrade button is hidden and replaced with an inline Link.Anchor inside the descriptive text, pointing to the change-plan page via a $derived upgradeHref.
• handleUpgrade (used by the desktop button) still independently calls resolve(...) rather than reusing the already-computed upgradeHref; the two stay in sync only by convention.
• No functional regressions introduced; the SSR initial value of isSmallViewport is false (desktop branch), which matches the server render and avoids hydration mismatches.

Confidence Score: 5/5

Safe to merge — the change is a targeted UI fix with no logic regressions.

Only P2-level observations remain (the handleUpgrade/upgradeHref duplication was already flagged in a previous review). No P0 or P1 issues found.

No files require special attention.
