HA only consults icon-translation state icons when the entity has no
static icon of its own (Entity.icon, if set, always wins -- see
homeassistant.helpers.entity's state_attributes construction). Audited
every entity with a labelled state/state_attributes catalog in
translations/en.json against its descriptor's icon= setting: every
select (cycles, courses, brightness levels, ...) and most sensors
already carry a fixed icon in code, so per-state icons there would be
silently shadowed. The three that don't -- air_purifier_fan's
preset_mode, machine_state, and connection_mode -- get one per value
here.
