Offline-first client routing via persisted segment-cache and fallback entrypoints

Offline-first client routing via persisted segment-cache and fallback entrypoints targets a $18.0B = 25M web & frontend developers x $720 avg annual spend on frameworks, hosting, dev tools and performance add-ons total addressable market with medium saturation and a year-over-year growth rate of 12% annual growth in web developer tooling, PaaS and edge-enabled runtimes.

Key trends driving demand: Offline-first UX -- demand for resilient experiences on flaky mobile/edge networks is increasing adoption of service-worker based solutions; Hybrid static+dynamic export -- frameworks and CDNs are pushing static fallback artifacts so parameterized routes can work without full pre-rendering; Edge runtimes & workers -- compute moving to edge enables richer client routing and cache replay strategies close to users; Framework-first primitives -- frameworks are incorporating data/runtime primitives (routing, cache) into core rails rather than relying on third-party libs.
