## Summary
- Fixed unescaped apostrophes in JSX text that were causing ESLint
errors
- These errors were preventing the production build from completing on
Railway
## Changes
- `app/[locale]/error.tsx`: Escaped apostrophe in "couldn't"
- `app/[locale]/not-found.tsx`: Escaped apostrophes in "you're" and
"couldn't"
- `app/[locale]/unauthorized/page.tsx`: Escaped apostrophe in "don't"
## Test plan
- [x] ESLint errors resolved locally
- [ ] Railway deployment succeeds after merge

## Summary
- Fixed avatar showing anonymous for several seconds on page load
- Eliminated hydration mismatch for authentication state
- Header now shows correct user state immediately
## Root Cause
AccountStateInitializer was running client-side in useEffect AFTER
hydration, causing:
1. Server renders anonymous state
2. Client hydrates with anonymous state
3. useEffect runs and updates state (causing the flash)
## Solution
- Read auth cookies server-side in layout.tsx
- Pass initial auth data as props to AccountStateInitializer
- Initialize Valtio state synchronously before first render
- Client-side cookie reading only as fallback
## Changes
- Added server-side cookie parsing in layout.tsx
- Modified AccountStateInitializer to accept initial auth data props
- Made Header component reactive with useSnapshot from Valtio
- State initialization happens synchronously, preventing the flash
## Test plan
- [x] Avatar renders correctly on first load
- [x] No anonymous avatar flash when logged in
- [x] Login/logout still works properly
- [x] State updates are reactive in the header

## Summary
- Fixes periodic production crashes (undici ECONNREFUSED ::1) by
bounding server cache size/lifetime and hardening server HTTP client.
### Root cause
- React server cache (cache(...)) held axios responses indefinitely
across many parameter combinations, causing slow memory growth until the
Next.js app router worker was OOM-killed. The main server then failed
IPC to the worker (ECONNREFUSED ::1:<port>).
### Changes
- `app/lib/data.ts`: Replace unbounded cache(...) with unstable_cache
and explicit keys; TTLs: 60s for teams/detail/favorites/user, 300s for
meta (jobs/skills/accessories/raids/version).
- `app/lib/api-utils.ts`: Add shared Axios instance with 15s timeout and
keepAlive http/https agents; apply to GET/POST/PUT/DELETE helpers.
- `pages/api/preview/[shortcode].ts`: Remove duplicate handler to dedupe
route; retain the .tsx variant using `NEXT_PUBLIC_SIERO_API_URL`.
### Notes
- Build currently has pre-existing app/pages route duplication errors;
out of scope here but unrelated to this fix.
- Ensure `NEXT_PUBLIC_SIERO_API_URL` and `NEXT_PUBLIC_SIERO_OAUTH_URL`
are set on Railway.
### Risk/impact
- Low risk; behavior is unchanged aside from bounded caching and
resilient HTTP.
- Cache TTLs can be tuned later if needed.
### Test plan
- Verify saved/teams/user pages load and revalidate after TTL.
- Validate API routes still proxy correctly; timeouts occur after ~15s
for hung upstreams.
- Monitor memory over several days; expect stable usage without steady
growth.
