// ANSI escape sequences. Covers:
|
|
// - CSI sequences per ECMA-48: `ESC [ param* intermediate* final` where
|
|
// param bytes are 0x30-0x3F (digits + `:;<=>?`), intermediate bytes are
|
|
// 0x20-0x2F (space + `!"#$%&'()*+,-./`), and final byte is 0x40-0x7E.
|
|
// This catches both vanilla SGR (`\x1b[36m`, `\x1b[0m`) and private-prefix
|
|
// sequences like `\x1b[?25l` (hide cursor) and `\x1b[?2004h` (bracketed
|
|
// paste) that tools like pnpm and Playwright emit. The narrower
|
|
// `[0-9;]*` pattern used to let those leak through and render as
|
|
// literal `[?25l` noise.
|
|
// - OSC sequences (hyperlinks, window title) terminated by ST or BEL:
|
|
// `\x1b]8;;url\x1b\\` or `\x1b]0;title\x07`. npm, pnpm, yarn and some
|
|
// make targets routinely emit the hyperlink variant.
