[#135] Remove hardcoded genre from discover page

[realproject7]

Removes hardcoded genre="fiction" prop from StoryCard in discover page. StoryCard already handles undefined genre gracefully (conditionally renders). Fixes #135

T2b Review: APPROVE

Hardcoded genre="fiction" removed from discover page. Verified src/app/page.tsx has no genre prop — already clean. StoryCard's existing conditional rendering handles undefined genre gracefully (the genre badge simply doesn't render).

Verdict: REQUEST CHANGES

Summary

The discover-page fix is correct, but the PR does not yet satisfy the full issue scope. Issue #135 explicitly requires removing the hardcoded genre from both src/app/discover/page.tsx and src/app/page.tsx, and this PR only changes the discover page.

Findings

• [high] Home page still needs the same hardcoded-genre audit required by issue #135
  • File: src/app/page.tsx
  • Suggestion: Re-check the home page and remove any hardcoded genre="fiction" usage there as well, or verify with code changes that no home-page StoryCard path still injects a fake genre. The issue acceptance criteria explicitly mention both pages.

Decision

Request changes because the PR only completes half of the required fix.

Verdict: APPROVE

Summary

I re-verified the home page directly: src/app/page.tsx already does not pass any genre prop to StoryCard, so the hardcoded genre issue existed only on the discover page. This PR removes that remaining hardcoded genre="fiction" usage, StoryCard already handles missing genre gracefully, and the required check passed.

Findings

• None.

Decision

Approve because the actual remaining bug is fixed and lint-and-typecheck passed.
