Draft
Conversation
- GPU-accelerate background overlay with will-change/translateZ(0) - Memoize KeyValueRow (rendered 100+ times per detail page) - Replace slow wildcard [class*='htw-'] CSS selectors with specific classes - Preload custom fonts to reduce FOUT - Reduce accent-glow blur radius from 20px to 10px Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Skip SSR OG data fetching for non-bot user agents (eliminates 3 network requests on every click from table to detail page) - Add Cache-Control header for real users (s-maxage=60, stale-while-revalidate) - Parallelize block explorer URL lookups in ContentDetailsCard - Memoize MessageSummaryRow (rendered 40-100x per table) - Enable Link prefetch on message table rows Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

There was a problem hiding this comment.
public, s-maxage=60 on the non-bot HTML is cache-unsafe here. Because the response varies by user agent but doesn’t have a safe cache key split, a CDN can cache the ogData: null human response and serve it to bots, breaking OG tags in the common user-visit-then-share flow. In #295 this is fixed by avoiding shared HTML caching on this route rather than relying on bot/human cache variation.
