Problem

Dates outside the pre-generated hot set must still be answerable. A dynamic endpoint computes them via Core on demand and emits headers that let Cloudflare cache the result immutably.

Acceptance criteria

Cold (date, system, calendar) requests are computed via Core and returned in the canonical envelope.
Responses set long immutable cache-control and a stable cache key per the input tuple.
A repeated cold request is served from cache rather than recomputed.
The dynamic path is covered by tests for a never-pre-generated date.

Notes

Responses are immutable per key; only a data-version bump should invalidate them.
