The Directions A and B letters and a data pack's media label were the two
Cesium text labels left, kept by an allow-list in noCesiumLabels.test.mjs.
Both now publish entries to the shared world-overlay host, and the
allow-list is gone, so any Cesium label in src is a test failure.
Directions publishes the letters to the directions-markers source; the
markers keep only their points. A clicked endpoint's letter hangs over the
surface that was clicked. One placed without a click stays hidden until its
ground-floor cell resolves, then requests a render, so a still camera shows
it; a cell that settles with no height falls back to the ellipsoid. Each
position is computed once.
A pack resource handle gains label(entry). The application passes its
shared overlay host to SceneDirector through dataPacks.overlayHost; without
one a media pack fails to load rather than drawing a native label. Each
labelled resource takes a source from a pool and returns it on dispose, as
the host never removes a source, so two presentations of one pack never
clear each other's labels and repeat loads add no sources. A label written
after dispose is ignored. The media label is protected, so it always draws
as before.
Live (Denver, keyless globe): a clicked A and a programmatic B both anchor
on their dots over 1.58 km ground. Documented in docs/CURRENT-STATE.md and
docs/DIRECTOR-DATA-PACKS.md.
