feat(globe): Navara's cinematic look by default

navaraScenePlan gains a pure `cinematic` plan, now the default of the app's
Navara mode (`?look=photoreal|minimal` picks the others): photoreal plus
volumetric clouds (low quality, layers from 1,500 m, no ground shadows),
ACES tone mapping, brighter stars and no sun shadow maps. From space, at
rest, the aerial perspective lights the globe from the atmosphere for a
real night side and terminator; it switches off below 1,000 km so the
Google tiles keep their baked light.

look.js builds the plan and keeps it current on frames Navara draws
anyway: the atmosphere's sun date follows the wall clock (the HUD's SUN
elevation), and the clouds hide above 4 km or over high ground in view,
parking their last image so the aerial perspective shows no ghosts.
