## ARRAY OF POSSIBLE QUOTES, WITH FORMATTING EMBEDDED
## With the current items.json configuration on a 16" MBP:
## - each line can be up to approximately 70 characters
##   (it's not mono-space, so there's a wide variability)
## - must use a \n to separate the 2 lines
##   (i.e. there's no automatic line-wrapping)

##############   TESTING STRINGS FOR LENGTH   ##############
## To evaluate line length for different configs:
## 1) comment out the `printf "${q[$id]}"` line below
## 2) uncomment the very last printf line below & ensure its
##    index id is set to 999
## 3) uncomment one of the `q[999]` that immediately follows
## 4) save this file
## 5) in your items.json set the `shellScriptTitledButton`'s
##    bordered entry to `true` then save that file
## - go through each of the following `q[999]...` lines,
##   ensuring that only one is uncommented at a time, 
##   save this file, then your items.json file to seee the 
##   results
## - when you have a good idea of the new length, ensure
##   that all the `q[999]...` are commented out, the very
##   last printf command is commented out, the
##   `printf "${q[$id]}"` entry is uncommented, and that
##   you've disabled the border over in items.json
