[#117] Fix min-h-screen double-nesting causing 44px overflow

[realproject7]

Fixes #117

Summary

• Root layout applies min-h-screen + pt-11 (44px nav offset) to the children wrapper
• Five pages also used min-h-screen on their own wrapper divs, causing a 44px scroll overflow
• Replaced min-h-screen with min-h-[calc(100vh-2.75rem)] on each affected page wrapper to account for the nav height

Files changed

• src/app/create/page.tsx — 2 wrapper divs (not-connected + published states)
• src/app/chain/page.tsx — 2 wrapper divs (not-connected + published states)
• src/app/dashboard/reader/page.tsx — 1 wrapper div (not-connected state)
• src/app/dashboard/writer/page.tsx — 1 wrapper div (not-connected state)
• src/app/discover/page.tsx — 1 wrapper div (database-unavailable state)

Test plan

• Verify no vertical scrollbar on each affected page when content fits viewport
• Verify empty/error states remain vertically centered
• Verify normal content pages (with form content) still scroll naturally when content exceeds viewport

Verdict: APPROVE

Summary

The PR fixes the double min-h-screen nesting exactly where issue #117 identified it, using min-h-[calc(100vh-2.75rem)] to preserve vertical centering without the 44px overflow. The change is narrow, consistent across the affected pages, and CI passed.

Findings

• None.

Decision

Approve because the implementation matches the acceptance criteria, stays focused on the overflow bug, and the lint-and-typecheck check passed.

T2b Review: REQUEST CHANGES

The fix is correct and consistent across the 5 listed files — calc(100vh - 2.75rem) properly accounts for the pt-11 navbar padding.

Required fix: src/app/story/[storylineId]/page.tsx has a NotFound component with the same min-h-screen double-nesting bug. Should be fixed in this PR for completeness.

Optional: The 2.75rem magic number is now in 8+ places. Consider a follow-up to extract it into a CSS custom property or Tailwind theme variable.

T2b Re-review: APPROVE

All 8 min-h-screen instances now fixed across 6 files, including the NotFound component in story/[storylineId]/page.tsx. Consistent calc(100vh - 2.75rem) replacement, flex centering preserved throughout.
