/**
 * scripts/inert — a dynamic value (a tool's name, a provider's call id) written
 * into a library line as an inline code span that cannot leave its line.
 *
 * Pattern: pure leaf.
 * Role:    core/ layer leaf, asked by the attachment's lines (`attachment.ts`)
 *          for every name and id they print.
 * Emits:   N/A.
 *
 * THE RULE. A provider may hand the library any string as a call id: line
 * breaks, a sentence, a fence. Interpolated as it is, a blank line in an id ends
 * the library's label paragraph, and the rest of the id renders as a paragraph
 * of its own — text nobody checked, under the answer, in the library's voice.
 * So a value is written as inline code:
 *
 * - every character that can end a line, turn the line's direction or hide
 *   (C0 and C1 controls, DEL, U+2028 and U+2029, format characters such as a
 *   bidi override or a zero-width joiner, a lone surrogate) is written as
 *   `\u{…}`, its code point in hex;
 * - at most {@link MAX_INERT_POINTS} code points are written, then `…`;
 * - the delimiter is one backtick longer than the longest run inside, with a
 *   space at either end when the value begins or ends with a backtick or a
 *   space (CommonMark's code-span rule), so nothing inside can close it.
 *
 * Inside a code span nothing is Markdown: no emphasis, no link, no HTML, no
 * line ending. The value is shown, never interpreted.
 *
 * @example
 * ```ts
 * inertCode('c1');                         // '`c1`'
 * inertCode('c1\n\nRevenue was 98765.');   // '`c1\u{a}\u{a}Revenue was 98765.`'
 * inertCode('a`b');                        // '``a`b``'
 * ```
