4 # The only sanctioned way to switch MuseHub's nginx upstream between blue and green.
5 # Accepts a slot name, constructs the correct nginx directive, validates, and reloads.

7 # Usage:
8 # sudo musehub-set-slot blue
9 # sudo musehub-set-slot green
10 #
11 # Called by deploy.sh automatically. For manual recovery:
12 # sudo musehub-set-slot blue ← blue is port 1337
13 # sudo musehub-set-slot green ← green is port 1338
