/**

* Truncates the given text "intelligently" based on the last period found near the max length.
|
|
*
|
|
* - If a period exists within the extended range (`maxLength` to `maxLength + maxExtension`),
|
|
* the function truncates after the closest period to `maxLength`.
|
|
* - If no period is found in the range, it truncates the text after the last period found in the max length of the text.
|
|
* - If no periods exist at all, it truncates at `maxLength` and appends ellipsis (`...`).
|
|
*
|
|
* @param {string} text - The input text to be truncated.
|
|
* @param {number} [maxLength=150] - The desired maximum length of the truncated text.
|
|
* @param {number} [minLength=120] - The minimum allowable length for the truncated text.
|
|
* @param {number} [maxExtension=10] - The maximum number of characters to extend beyond `maxLength` to find a period.
|
|
* @returns {string} - The truncated text.
