Be lazy, but with strategy
summary
Compares concrete strategies for Angular lazy loading: uses router preloading hooks and observables to delay fetches, measures connection speed by timing downloads of known assets, and inspects navigator hints for device heuristics. Builds a working service that implements a custom preloading strategy and a simple transition matrix based on Markov Chains, which in one case preloads about six modules out of ~60 and noticeably improves perceived navigation speed.
