<p>I appreciate you taking the time to explain this in such detail. If I understand correctly, this project is for the website UX/accounts, and it depends on the Mapnik project for editing, the OSMF project for providing the tiles, and the LeafletJS project for drawing the OSMF tiles on screen. High-DPI tiles cannot be provided at the source because it is a complex process.</p>
<p>At the risk of forgetting something important, can I propose this website adds a "Standard 2x" layer that people can choose, a special mode for high-DPI fans who prefer a crisp map over larger street names? It is not ideal with the small names, but neither is a low-DPI map on a high-DPI screen.</p>
<p>It can be constructed by using the existing tiles at half their size.</p>
<p>The layer can be constructed using the <code>tileSize</code> and <code>zoomOffset</code> options like so:</p>
<div class="highlight highlight-source-js"><pre><span class="pl-en">tileLayer</span><span class="pl-kos">(</span><span class="pl-s">'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png'</span><span class="pl-kos">,</span> <span class="pl-kos">{</span>
    <span class="pl-c1">tileSize</span>: <span class="pl-c1">128</span><span class="pl-kos">,</span>
    <span class="pl-c1">zoomOffset</span>: <span class="pl-c1">1</span>
<span class="pl-kos">}</span><span class="pl-kos">)</span></pre></div>

<p>It's very pleasant to look at on a high-DPI screen, especially when you care more about the lay than the name of the land.</p>
<p>I'm getting ahead of myself a little here, but you can also choose to add it as a toggle, so it can optionally apply to other layers who's map tile sources were painstakingly set up in the "low-DPI era" as well.</p>
