The 1.12 client only parses lowercase |cAARRGGBB color escapes; the
uppercase |C codes in the Title rendered as literal escape text in the
in-game AddOns list. Lowercasing the escape markers makes the coloured
'Necrosis LdC' title render correctly (matches the normalization the
manifest resolver already applies to the catalog).
