//! Inline raw-HTML edge cases — the constructs that don't fit the
//! ordinary open/close tag shape but still pass through verbatim:
//!
//!   - Processing instructions: `<?…?>`
//!   - Declarations: `<!LETTER…>`
//!   - CDATA sections: `<![CDATA[…]]>`
//!   - Short HTML comment forms: `<!-->` (empty body) and `<!--->`
//!     (single-hyphen body)
//!   - Malformed attribute quoting that should reject as text rather
//!     than match as inline HTML.
