"""Generate the test strings for the M1 settings spike (docs/SETTINGS_SPIKE.md). Length strings look like N=1000|abcdef...P0050...P0100...xyzEND "N=|" says how long the string should be, a marker "P" sits at every 50th character, and "END" closes it. If the phone app cuts a string, the watch shows a wrong length and no "END"; the last marker it shows tells roughly where the cut happened. Only letters, digits, "=", "|" are used, so the length tests don't also test character handling. special.txt holds the characters that may be rejected (& < > \\ " { } %), non-ASCII text, a fake otpauth URI and a JSON fragment.
