This change adds JSDoc-style comments to several functions and classes across the codebase to improve readability and maintainability. Comments were added to: - `src/SEQTA.ts`: Explained the `init()` function. - `src/seqta/utils/waitForElm.ts`: Detailed the `waitForElm()` function, its parameters, and behavior. - `src/seqta/utils/stringToHTML.ts`: Clarified the `stringToHTML()` function, including its sanitization and styling features. - `src/seqta/utils/delay.ts`: Added a brief explanation for the `delay()` utility. - `src/seqta/utils/mutex.ts`: Documented the `Mutex` class and its `acquire` method (renamed from `lock`), explaining its asynchronous locking mechanism and the role of the returned unlock function.

/**
|
|
* Converts an HTML string into a DOM element, with sanitization and optional styling.
|
|
*
|
|
* This function first sanitizes the input HTML string using DOMPurify to prevent XSS attacks.
|
|
* The sanitization process allows 'onclick' attributes and specific URI schemes.
|
|
* Then, it parses the sanitized string into an HTML document and returns its body.
|
|
* Optionally, it can apply predefined CSS styles to the body element.
|
|
*
|
|
* @param {string} str The HTML string to convert.
|
|
* @param {boolean} [styles=false] Whether to apply predefined styles to the document body.
|
|
* @returns {HTMLElement} The body element of the parsed and sanitized HTML document.
