Rolldown's default `inlineConst: 'smart'` only inlines constants in conditions, so frequently used `@sentry/conventions` strings end up both as a variable and as literal copies. Inlining everywhere grows the raw output but shrinks the gzipped CDN bundles by ~90-170 B each. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Why: Rolldown's default
inlineConst: { mode: 'smart' }inlines constants only inside conditions. Frequently used strings, mostly from@sentry/conventions, therefore end up both as a variable and as literal copies:sentry.opis one variable plus about 10 literals inbundle.tracing.min.js. Withmode: 'all'every use becomes a literal. Raw size grows, but gzip handles repeated literals better than variable references, so what users download gets smaller:.min.jsbundlesbundle.min.jsbundle.tracing.min.jsbundle.tracing.replay.min.jsbundle.tracing.logs.metrics.min.jsinlineConst: falsewent the other way: −3.9 KB raw, +261 B gzip.pass: 2made no difference. This only touches the CDN bundle config, not npm builds.How to review: Single config line. I ran the browser integration tests against
bundle_tracing_replay_min: 641 passed, and 1 failed. That one (web-vitals-cls-without-array-at) also fails ondeveloplocally.🤖 Generated with Claude Code
