This is a fair point, and includes manuscripts used in worship (e.g, prajnaparamita mss written with gold letters). I should qualify my earlier statement to say that ranjana is an uncommon script, reserved for more specialized and elevated manuscripts, especially those regularly used in ritual worship (often of the manuscript itself).

Actually, besides palm leaf, some of the ones I’ve seen are very ornate, written in silver or gold on black-painted paper similar to Tibetan mthing shog.

I have also seen manuscripts of the very same works noted above in Rañjana. On palm leaf if I remember correctly.

All my best,
