The fine 0.4 degree blur kept the residual glow of unresolved stars as
mottled patches at the band's edges. Blend towards a 2 degree blur where
the coarse copy is faint (smoothstep over 0.5-8 % of the range), so the
core keeps its dust lanes and the faint sky goes smooth. Faces 85 -> 62 kB.

Resolve conflicts with #1234: keep redirect: 'manual' on both DATEX
fetches and keep main's 30 s TARKTEE_FETCH_TIMEOUT_MS. Drop this
branch's 15 s constant and its import, which auto-merged into a
duplicate export. Keep both sets of Estonia tests and drop the 15 s
claim from the changelog fragment.

Away from the galactic plane the ESO panorama keeps a mottled glow of
unresolved stars and dust. With the black level at the darkest quarter of
the sky and a hard cut, it showed as grey clouds with black holes around
the globe. The black level now sits at the median sky and eases in with a
soft knee on luminance, keeping each pixel's hue: high galactic latitudes
are black, the band keeps its glow. Faces shrink from 247 to 85 KB.
The changelog fragment also notes the anime fade and the new asset weight.

- Default backoff is 30 min, longer than the 15-minute catalog refresh,
so a failing Kartverket costs one attempt per backoff, not per refresh.
- A point a 200 answer leaves out is cached as no height (6 h TTL)
instead of being asked again, and waited on, every refresh.
- Only 408, 429 and 5xx stop the lookup; any other 4xx marks that
request's points as no height and the lookup carries on.
- Each request has its own 10 s timeout inside the shared 30 s deadline;
a lookup cut short only by the deadline resumes without a backoff.
- The lane waits only on a cold cache (>10% of cameras missing); a few
new cameras or expired misses are looked up in the background.
- applyVegvesenGroundHeights skips cameras without finite coordinates,
so it really never throws.
- clearKartverketHeightCache bumps a generation, so a lookup started
before a clear cannot write to the cache, backoff or pending slot.
- Credit and DATA_SOURCES note the modification (water set to 0 m,
rounded to 0.1 m) as CC BY 4.0 asks; docs match the stop rules.
- Tests for the deadline being shared, per-request timeouts, 503,
oversized and non-JSON bodies, 4xx, left-out points, Retry-After end
to end, overlapping refreshes, the warm-cache wait, bad coordinates,
the cache-clear generation and the loader's wait budget.
