N-05: the conditional-validator key was a colon join over components that may
themselves contain colons, so two distinct valid bindings could collide and one
definition's ETag could be prepared for another. The key is now a validated,
byte-bounded fixed tuple encoded with JSON.stringify.
N-09: capture localStorage exactly once and compare StorageEvent.storageArea
against that object identity, so a pulse from sessionStorage or any other area
is rejected instead of matching on key and value alone. The pulse key is
registered in the storage registry as CACHE_INVALIDATION_PULSE.
N-10: race loadPage against the caller signal and re-check before observing a
page, so a non-cooperative loader can neither hold loadAll forever nor have a
post-abort completion accumulated into a successful result.
