+
+Oh, hello! Funny seeing you here.
+
+I appreciate your enthusiasm, but you aren't going to find much down here.
+There certainly aren't clues to any of the puzzles. The best surprises don't
+even appear in the source until you unlock them for real.
+
+Please be careful with automated requests; I'm not Google, and I can only take
+so much traffic. Please be considerate so that everyone gets to play.
+
+If you're curious about how Advent of Code works, it's running on some custom
+Perl code. Other than a few integrations (auth, analytics, ads, social media),
+I built the whole thing myself, including the design, animations, prose, and
+all of the puzzles.
+
+The puzzles are most of the work; the easiest ones take 3-4 hours each, but the
+harder ones take 6-8 hours, and a few even longer than that. A lot of effort
+went into building this thing - I hope you're enjoying playing it as much as I
+enjoyed making it for you!
+
+If you'd like to hang out, I'm @ericwastl on Twitter.

+<article class="day-desc"><h2>--- Day 3: No Matter How You Slice It ---</h2><p>The Elves managed to locate the chimney-squeeze prototype fabric for Santa's suit (thanks to <span title="WAS IT YOU">someone</span> who helpfully wrote its box IDs on the wall of the warehouse in the middle of the night). Unfortunately, anomalies are still affecting them - nobody can even agree on how to <em>cut</em> the fabric.</p>
+<p>The whole piece of fabric they're working on is a very large square - at least <code>1000</code> inches on each side.</p>
+<p>Each Elf has made a <em>claim</em> about which area of fabric would be ideal for Santa's suit. All claims have an ID and consist of a single rectangle with edges parallel to the edges of the fabric. Each claim's rectangle is defined as follows:</p>
+<ul>
+<li>The number of inches between the left edge of the fabric and the left edge of the rectangle.</li>
+<li>The number of inches between the top edge of the fabric and the top edge of the rectangle.</li>
+<li>The width of the rectangle in inches.</li>
+<li>The height of the rectangle in inches.</li>
+</ul>
+<p>A claim like <code>#123 @ 3,2: 5x4</code> means that claim ID <code>123</code> specifies a rectangle <code>3</code> inches from the left edge, <code>2</code> inches from the top edge, <code>5</code> inches wide, and <code>4</code> inches tall. Visually, it claims the square inches of fabric represented by <code>#</code> (and ignores the square inches of fabric represented by <code>.</code>) in the diagram below:</p>
+<pre><code>...........
+...........
+...#####...
+...#####...
+...#####...
+...#####...
+...........
+...........
+...........
+</code></pre>
+<p>The problem is that many of the claims <em>overlap</em>, causing two or more claims to cover part of the same areas. For example, consider the following claims:</p>
+<pre><code>#1 @ 1,3: 4x4
+#2 @ 3,1: 4x4
+#3 @ 5,5: 2x2
+</code></pre>
+<p>Visually, these claim the following areas:</p>
+<pre><code>........
+...2222.
+...2222.
+.11XX22.
+.11XX22.
+.111133.
+.111133.
+........
+</code></pre>
+<p>The four square inches marked with <code>X</code> are claimed by <em>both <code>1</code> and <code>2</code></em>. (Claim <code>3</code>, while adjacent to the others, does not overlap either of them.)</p>
+<p>If the Elves all proceed with their own plans, none of them will have enough fabric. <em>How many square inches of fabric are within two or more claims?</em></p>
+</article>
+<p>Your puzzle answer was <code>111266</code>.</p><article class="day-desc"><h2 id="part2">--- Part Two ---</h2><p>Amidst the chaos, you notice that exactly one claim doesn't overlap by even a single square inch of fabric with any other claim. If you can somehow draw attention to it, maybe the Elves will be able to make Santa's suit after all!</p>
+<p>For example, in the claims above, only claim <code>3</code> is intact after all claims are made.</p>
+<p><em>What is the ID of the only claim that doesn't overlap?</em></p>
+</article>
+<p>Your puzzle answer was <code>266</code>.</p><p class="day-success">Both parts of this puzzle are complete! They provide two gold stars: **</p>
