-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 a massive company, 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, 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; preparing a new calendar and a new set of
-puzzles each year takes all of my free time for 4-5 months. 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@hachyderm.io on Mastodon and
-@ericwastl on Twitter.

-<article class="day-desc"><h2>--- Day 2: Cube Conundrum ---</h2><p>You're launched high into the atmosphere! The apex of your trajectory just barely reaches the surface of a large island floating in the sky. You gently land in a fluffy pile of leaves. It's quite cold, but you don't see much snow. An Elf runs over to greet you.</p>
-<p>The Elf explains that you've arrived at <em>Snow Island</em> and apologizes for the lack of snow. He'll be happy to explain the situation, but it's a bit of a walk, so you have some time. They don't get many visitors up here; <span title="No, the Elf's name is not 'WOPR'. It's Joshua.">would you like to play a game</span> in the meantime?</p>
-<p>As you walk, the Elf shows you a small bag and some cubes which are either red, green, or blue. Each time you play this game, he will hide a secret number of cubes of each color in the bag, and your goal is to figure out information about the number of cubes.</p>
-<p>To get information, once a bag has been loaded with cubes, the Elf will reach into the bag, grab a handful of random cubes, show them to you, and then put them back in the bag. He'll do this a few times per game.</p>
-<p>You play several games and record the information from each game (your puzzle input). Each game is listed with its ID number (like the <code>11</code> in <code>Game 11: ...</code>) followed by a semicolon-separated list of subsets of cubes that were revealed from the bag (like <code>3 red, 5 green, 4 blue</code>).</p>
-<p>For example, the record of a few games might look like this:</p>
-<pre><code>Game 1: 3 blue, 4 red; 1 red, 2 green, 6 blue; 2 green
-Game 2: 1 blue, 2 green; 3 green, 4 blue, 1 red; 1 green, 1 blue
-Game 3: 8 green, 6 blue, 20 red; 5 blue, 4 red, 13 green; 5 green, 1 red
-Game 4: 1 green, 3 red, 6 blue; 3 green, 6 red; 3 green, 15 blue, 14 red
-Game 5: 6 red, 1 blue, 3 green; 2 blue, 1 red, 2 green
-</code></pre>
-<p>In game 1, three sets of cubes are revealed from the bag (and then put back again). The first set is 3 blue cubes and 4 red cubes; the second set is 1 red cube, 2 green cubes, and 6 blue cubes; the third set is only 2 green cubes.</p>
-<p>The Elf would first like to know which games would have been possible if the bag contained <em>only 12 red cubes, 13 green cubes, and 14 blue cubes</em>?</p>
-<p>In the example above, games 1, 2, and 5 would have been <em>possible</em> if the bag had been loaded with that configuration. However, game 3 would have been <em>impossible</em> because at one point the Elf showed you 20 red cubes at once; similarly, game 4 would also have been <em>impossible</em> because the Elf showed you 15 blue cubes at once. If you add up the IDs of the games that would have been possible, you get <code><em>8</em></code>.</p>
-<p>Determine which games would have been possible if the bag had been loaded with only 12 red cubes, 13 green cubes, and 14 blue cubes. <em>What is the sum of the IDs of those games?</em></p>
-</article>
-<p>Your puzzle answer was <code>2101</code>.</p><article class="day-desc"><h2 id="part2">--- Part Two ---</h2><p>The Elf says they've stopped producing snow because they aren't getting any <em>water</em>! He isn't sure why the water stopped; however, he can show you how to get to the water source to check it out for yourself. It's just up ahead!</p>
-<p>As you continue your walk, the Elf poses a second question: in each game you played, what is the <em>fewest number of cubes of each color</em> that could have been in the bag to make the game possible?</p>
-<p>Again consider the example games from earlier:</p>
-<pre><code>Game 1: 3 blue, 4 red; 1 red, 2 green, 6 blue; 2 green
-Game 2: 1 blue, 2 green; 3 green, 4 blue, 1 red; 1 green, 1 blue
-Game 3: 8 green, 6 blue, 20 red; 5 blue, 4 red, 13 green; 5 green, 1 red
-Game 4: 1 green, 3 red, 6 blue; 3 green, 6 red; 3 green, 15 blue, 14 red
-Game 5: 6 red, 1 blue, 3 green; 2 blue, 1 red, 2 green
-</code></pre>
-<ul>
-<li>In game 1, the game could have been played with as few as 4 red, 2 green, and 6 blue cubes. If any color had even one fewer cube, the game would have been impossible.</li>
-<li>Game 2 could have been played with a minimum of 1 red, 3 green, and 4 blue cubes.<li>
-<li>Game 3 must have been played with at least 20 red, 13 green, and 6 blue cubes.</li>
-<li>Game 4 required at least 14 red, 3 green, and 15 blue cubes.</li>
-<li>Game 5 needed no fewer than 6 red, 3 green, and 2 blue cubes in the bag.</li>
-</ul>
-<p>The <em>power</em> of a set of cubes is equal to the numbers of red, green, and blue cubes multiplied together. The power of the minimum set of cubes in game 1 is <code>48</code>. In games 2-5 it was <code>12</code>, <code>1560</code>, <code>630</code>, and <code>36</code>, respectively. Adding up these five powers produces the sum <code><em>2286</em></code>.</p>
-<p>For each game, find the minimum set of cubes that must have been present. <em>What is the sum of the power of these sets?</em></p>
