//! Which elements carry which values at the low-cardinality declaration words?

//!
|
|
//! `decl_entry_diff` found nothing separating `ptframe1`/`ptframe2` except their
|
|
//! NAME — +0x00 and +0x08 are the name string ("ptfr", ".t32"), so those two hits
|
|
//! are a false positive of that test, not a field.
|
|
//!
|
|
//! The remaining candidates for a per-element mode flag are the words with few

|
//! distinct values: +0x28 (3) and +0x2C (6). This prints who has what.
