+this license.
  Some devices are designed to deny users access to install or run
 modified versions of the software inside them, although the manufacturer
 can do so.  This is fundamentally incompatible with the aim of
 protecting users' freedom to change the software.  The systematic
 pattern of such abuse occurs in the area of products for individuals to
 use, which is precisely where it is most unacceptable.  Therefore, we
 have designed this version of the GPL to prohibit the practice for those
 products.  If such problems arise substantially in other domains, we
 stand ready to extend this provision to those domains in future versions
 of the GPL, as needed to protect the freedom of users.
  Finally, every program is threatened constantly by software patents.
 States should not allow patents to restrict development and use of
 software on general-purpose computers, but in those that do, we wish to
 avoid the special danger that patents applied to a free program could
 make it effectively proprietary.  To prevent this, the GPL assures that
 patents cannot be used to render the program non-free.

 # @strudel.cycles/embed
 This package contains a embeddable web component for the Strudel REPL.
 ## Usage
 Either install with `npm i @strudel.cycles/embed` or just use a cdn to import the script:
 ```html
 <script src="https://unpkg.com/@strudel.cycles/embed@latest"></script>
 <strudel-repl>
  <!--

    .off(1/8,x=>x.add(12).color('#215CB6'))
    .slow(2)
    .legato(sine.range(0.3, 2).slow(28))
