1//! C1 control bytes (`0x80..=0x9f`).
2//!
3//! ## Category
4//!
5//! C1 controls are the 8-bit single-byte forms of terminal controls such as DCS,
6//! CSI, ST, OSC, PM, and APC.
7//!
8//! ## 7-bit versus 8-bit forms
9//!
10//! Each C1 byte has a 7-bit fallback spelling `ESC` followed by `byte - 0x40`.
11//! For example, [`CSI`] is `0x9b` while the 7-bit CSI introducer is the two-byte
12//! sequence `ESC [`.
13//!
14//! ```text
15//! 8-bit:  9B        CSI
16//! 7-bit:  1B 5B     ESC [
17//!        ─┬ ─┬
18//!        ESC final
19//! ```
20//!
21//! ## Mode interaction
22//!
23//! The byte constants do not enable any terminal mode. The tokenizer recognizes
24//! the C1 introducers directly and also recognizes their 7-bit `ESC` forms.
