multi-areas

how auth/metadata grabbing will work if/when we (have to?) switch to multi-regions

first run

second run

got cached stuff from first run now

where the areas actually come from

grpc api

use the grpc/protobuf api made for this purpose https://api.annex.radiko.jp/radiko.ProgramService/ListStations

downloader script
self-written .proto file to decode it
decode done with le top sekrit gchq software (cyberchef)
but hmm, then i would have to figure out how to properly deal with protobufs
no prior art in yt-dlp that i can copy from afaik

mobile site

alternatively, some pages on the new mobile site have area details in the big json blob
todo: find example
