* Größe/Farbe steuert CSS über die .icon-Klasse bzw. currentColor).
*
* NUR CLI/Build — nie im Request-Pfad. Besucher laden ausschließlich die lokalen
* SVGs (inline via icon()-Helper), niemals ein CDN.

* Aufruf: php bin/icons-add.php pause-fill play-fill arrow-right ...
* Icon-Namen siehe https://icons.getbootstrap.com (Dateiname ohne .svg).
