From the code review of #768:
- view.js measured the camera's height above ground with globe.getHeight,
but Google 3D hides the globe, so coverage picked its zoom from the
ellipsoidal height. Over a high city (Denver, ~1,600 m) a camera 500 m up
read 2,100 m: coverage stayed at z12/z13, whose tiles are too big to cast,
and lines stayed draped on the roofs. With the globe hidden, the bare-earth
height from the ground caster now answers; coverage re-picks its zoom when
the surface mode changes. Verified in Denver: terrain mode, z14, cast lines.
The core's surface check uses the same helper (and no longer subtracts the
2 m lift from the camera height).
- castTile rebuilt a tile even when no line could be cast (terrain proxy
down, tile too big); it now leaves such tiles as they are.
- The feature gate read Street Level's share token as a literal `0`; it now
takes it from LAYER_STATE_REGISTRY, since a rebase can reassign it.
New view.test.mjs covers the shown-globe, hidden-globe and no-sample cases.

Street Level is now a provider-neutral layer modelled on the iD editor's
photo overlay. The core owns what every imagery provider shares: the
enable state and a switch per provider, the imagery filter (360°/flat and
captured-since in relative days), one click handler routed by pick prefix,
one viewer host that mounts whichever provider's viewer adapter owns the
open image, the position marker, camera follow, one on-globe credit per
active provider, and share-link parameters (one bit per provider plus the
filter). Providers implement the contract in registry.js: coverage,
sequences, nearest-image lookup and a viewer adapter emitting a common
pose. Mapillary is the only registered provider; Google Street View,
KartaView and Panoramax slot in beside it.
Panel: a PROVIDERS chip row (one chip per registered provider, keyless
chips read as errors), relative-day SINCE options, a provider-neutral
caption whose link label follows the provider, and no vendor mark in the
header. The panel inner is a rail scroller like CCTV's.
Tests cover the registry, params codec, filter, pick router, UI-state
composition, the provider definition and coverage-tile decoding; the QA
harness switches the provider off and on and checks the filter.
