GET /api/conditions surfaces what the backend already computes: moon
phase, veil thinness, geomagnetic state — junk lon degrades to moon-only
instead of a 422, missing NOAA data means fewer lines, never an error.
VeilConditions renders it in the séance side column, polling every 10 min.
ModeHint: one in-fiction line per mode after 15s of an unused sensor,
dismissed forever via localStorage. Error copy in evp/radio now
detect-and-redirects (mic denied -> 'the board needs no ear'; no WebUSB
-> try EVP) instead of dead-ending.
No geolocation prompt from the conditions strip — asking for location
from a passive readout would be hostile; ?lon= stays supported for
callers that have it.
