Stealth-mode North Star! Rebranding in secret with feature flags
summary
Claim: a full product rebrand ships in 10 weeks without alerting most of the company. Implementation: use feature flags (boolean, prerequisite, multivariate) via launch darkly to gate theming, fonts, design tokens, HTML templates and favicons. Built a theme provider that sets data attributes at runtime, preloads the Inter variable font only when enabled, boots server-side flags into Go templates to avoid FOUC, and tests combinations in production like a staging playground — it works.
