<p class="apology-title">If you've been reading this message for more
than a second or two, then <strong>this WebAssembly puzzle doesn't
seem to be working in your web browser</strong>. Sorry!</p>
<p>
<details>
<summary>More information</summary>
<p>Most modern browsers should support WASM. I've had reports of success from:
<ul>
<li>Firefox 87.0</li>
<li>Chrome 89.0.4389.114</li>
<li>Safari 14.0.3 (16610.4.3.1.7)</li>
<li>Edge 89.0.774.68</li>
<li>Opera 75.0.3969.149</li>
</ul></p>
<p>If this puzzle isn't working in one of those browsers (or a later
version), check to see whether you have any local configuration that
might have turned off WebAssembly completely, or some kind of blocking
software that might have prevented the WASM code from being downloaded
in the first place.</p>
<p>(For example, in Firefox, it's possible to turn off WASM completely
by setting <code>javascript.options.wasm</code> to <code>false</code>
in the <code>about:config</code> interface. If you've done that, or
something analogous in another browser, this puzzle won't run.)</p>
<p>In other browsers, the problem might be that WebAssembly isn't
supported at all (for example, Internet Explorer 11), or that a
browser update is needed.</p>
<p>If you think that your browser <em>should</em> support WebAssembly,
but this puzzle still isn't running, then please report the problem,
including <strong>as much diagnostic information as you can
find</strong>.</p>
<p>In particular, try opening your browser's Javascript error console
and then reloading this page, and tell me if it reports any error
messages.</p>
<p>Also, if your browser has a network diagnostic tab, try the same
experiment, to make sure it is successfully loading both of the
auxiliary files <code>${filename}.js</code> and
<code>${filename}.wasm</code>.</p>
