+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 on Twitter.

+<article class="day-desc"><h2>--- Day 7: Handy Haversacks ---</h2><p>You land at the regional airport in time for your next flight. In fact, it looks like you'll even have time to grab some food: all flights are currently delayed due to <em>issues in luggage processing</em>.</p>
+<p>Due to recent aviation regulations, many rules (your puzzle input) are being enforced about bags and their contents; bags must be color-coded and must contain specific quantities of other color-coded bags. Apparently, nobody responsible for these regulations considered how long they would take to enforce!</p>
+<p>For example, consider the following rules:</p>
+<pre><code>light red bags contain 1 bright white bag, 2 muted yellow bags.
+dark orange bags contain 3 bright white bags, 4 muted yellow bags.
+bright white bags contain 1 shiny gold bag.
+muted yellow bags contain 2 shiny gold bags, 9 faded blue bags.
+shiny gold bags contain 1 dark olive bag, 2 vibrant plum bags.
+dark olive bags contain 3 faded blue bags, 4 dotted black bags.
+vibrant plum bags contain 5 faded blue bags, 6 dotted black bags.
+faded blue bags contain no other bags.
+dotted black bags contain no other bags.
+</code></pre>
+<p>These rules specify the required contents for 9 bag types. In this example, every <code>faded blue</code> bag is empty, every <code>vibrant plum</code> bag contains 11 bags (5 <code>faded blue</code> and 6 <code>dotted black</code>), and so on.</p>
+<p>You have a <code><em>shiny gold</em></code> bag. If you wanted to carry it in at least one other bag, how many different bag colors would be valid for the outermost bag? (In other words: how many colors can, eventually, contain at least one <code>shiny gold</code> bag?)</p>
+<p>In the above rules, the following options would be available to you:</p>
+<ul>
+<li>A <code>bright white</code> bag, which can hold your <code>shiny gold</code> bag directly.</li>
+<li>A <code>muted yellow</code> bag, which can hold your <code>shiny gold</code> bag directly, plus some other bags.</li>
+<li>A <code>dark orange</code> bag, which can hold <code>bright white</code> and <code>muted yellow</code> bags, either of which could then hold your <code>shiny gold</code> bag.</li>
+<li>A <code>light red</code> bag, which can hold <code>bright white</code> and <code>muted yellow</code> bags, either of which could then hold your <code>shiny gold</code> bag.</li>
+</ul>
+<p>So, in this example, the number of bag colors that can eventually contain at least one <code>shiny gold</code> bag is <code><em>4</em></code>.</p>
+<p><em>How many bag colors can eventually contain at least one <code>shiny gold</code> bag?</em> (The list of rules is quite long; make sure you get all of it.)</p>
+</article>
+<p>Your puzzle answer was <code>242</code>.</p><article class="day-desc"><h2 id="part2">--- Part Two ---</h2><p>It's getting pretty expensive to fly these days - not because of ticket prices, but because of the ridiculous number of bags you need to buy!</p>
+<p>Consider again your <code>shiny gold</code> bag and the rules from the above example:</p>
+<ul>
+<li><code>faded blue</code> bags contain <code>0</code> other bags.</li>
+<li><code>dotted black</code> bags contain <code>0</code> other bags.</li>
+<li><code>vibrant plum</code> bags contain <code>11</code> other bags: 5 <code>faded blue</code> bags and 6 <code>dotted black</code> bags.</li>
+<li><code>dark olive</code> bags contain <code>7</code> other bags: 3 <code>faded blue</code> bags and 4 <code>dotted black</code> bags.</li>
+</ul>
+<p>So, a single <code>shiny gold</code> bag must contain 1 <code>dark olive</code> bag (and the 7 bags within it) plus 2 <code>vibrant plum</code> bags (and the 11 bags within <em>each</em> of those): <code>1 + 1*7 + 2 + 2*11</code> = <code><em>32</em></code> bags!</p>
+<p>Of course, the actual rules have a <span title="100%">small</span> chance of going several levels deeper than this example; be sure to count all of the bags, even if the nesting becomes topologically impractical!</p>
+<p>Here's another example:</p>
+<pre><code>shiny gold bags contain 2 dark red bags.
+dark red bags contain 2 dark orange bags.
+dark orange bags contain 2 dark yellow bags.
+dark yellow bags contain 2 dark green bags.
+dark green bags contain 2 dark blue bags.
+dark blue bags contain 2 dark violet bags.
+dark violet bags contain no other bags.
+</code></pre>
+<p>In this example, a single <code>shiny gold</code> bag must contain <code><em>126</em></code> other bags.</p>
+<p><em>How many individual bags are required inside your single <code>shiny gold</code> bag?</em></p>
+</article>
+<p>Your puzzle answer was <code>176035</code>.</p><p class="day-success">Both parts of this puzzle are complete! They provide two gold stars: **</p>
+<p>At this point, you should <a href="/2020">return to your Advent calendar</a> and try another puzzle.</p>

-<article class="day-desc"><h2>--- Day 4: Passport Processing ---</h2><p>You arrive at the airport only to realize that you grabbed your North Pole Credentials instead of your passport. While these documents are extremely similar, North Pole Credentials aren't issued by a country and therefore aren't actually valid documentation for travel in most of the world.</p>
-<p>It seems like you're not the only one having problems, though; a very long line has formed for the automatic passport scanners, and the delay could upset your travel itinerary.</p>
-<p>Due to some questionable network security, you realize you might be able to solve both of these problems at the same time.</p>
-<p>The automatic passport scanners are slow because they're having trouble <em>detecting which passports have all required fields</em>. The expected fields are as follows:</p>
-<ul>
-<li><code>byr</code> (Birth Year)</li>
-<li><code>iyr</code> (Issue Year)</li>
-<li><code>eyr</code> (Expiration Year)</li>
-<li><code>hgt</code> (Height)</li>
-<li><code>hcl</code> (Hair Color)</li>
-<li><code>ecl</code> (Eye Color)</li>
-<li><code>pid</code> (Passport ID)</li>
-<li><code>cid</code> (Country ID)</li>
-</ul>
-<p>Passport data is validated in batch files (your puzzle input). Each passport is represented as a sequence of <code>key:value</code> pairs separated by spaces or newlines. Passports are separated by blank lines.</p>
-<p>Here is an example batch file containing four passports:</p>
-<pre><code>ecl:gry pid:860033327 eyr:2020 hcl:#fffffd
-byr:1937 iyr:2017 cid:147 hgt:183cm
-
-iyr:2013 ecl:amb cid:350 eyr:2023 pid:028048884
-hcl:#cfa07d byr:1929
-
-hcl:#ae17e1 iyr:2013
-eyr:2024
-ecl:brn pid:760753108 byr:1931
-hgt:179cm
-
-hcl:#cfa07d eyr:2025 pid:166559648
-iyr:2011 ecl:brn hgt:59in
-</code></pre>
-<p>The first passport is <em>valid</em> - all eight fields are present. The second passport is <em>invalid</em> - it is missing <code>hgt</code> (the Height field).</p>
-<p>The third passport is interesting; the <em>only missing field</em> is <code>cid</code>, so it looks like data from North Pole Credentials, not a passport at all! Surely, nobody would mind if you made the system temporarily ignore missing <code>cid</code> fields.  Treat this "passport" as <em>valid</em>.</p>
-<p>The fourth passport is missing two fields, <code>cid</code> and <code>byr</code>. Missing <code>cid</code> is fine, but missing any other field is not, so this passport is <em>invalid</em>.</p>
-<p>According to the above rules, your improved system would report <code><em>2</em></code> valid passports.</p>
-<p>Count the number of <em>valid</em> passports - those that have all required fields. Treat <code>cid</code> as optional. <em>In your batch file, how many passports are valid?</em></p>
-</article>
-<p>Your puzzle answer was <code>247</code>.</p><article class="day-desc"><h2 id="part2">--- Part Two ---</h2><p>The line is moving more quickly now, but you overhear airport security talking about how passports with invalid data are getting through. Better add some data validation, quick!</p>
-<p>You can continue to ignore the <code>cid</code> field, but each other field has <span title="GLORY TO ARSTOTZKA">strict rules</span> about what values are valid for automatic validation:</p>
-<ul>
-<li><code>byr</code> (Birth Year) - four digits; at least <code>1920</code> and at most <code>2002</code>.</li>
-<li><code>iyr</code> (Issue Year) - four digits; at least <code>2010</code> and at most <code>2020</code>.</li>
-<li><code>eyr</code> (Expiration Year) - four digits; at least <code>2020</code> and at most <code>2030</code>.</li>
-<li><code>hgt</code> (Height) - a number followed by either <code>cm</code> or <code>in</code>:
-  <ul>
-  <li>If <code>cm</code>, the number must be at least <code>150</code> and at most <code>193</code>.</li>
-  <li>If <code>in</code>, the number must be at least <code>59</code> and at most <code>76</code>.</li>
-  </ul>
-</li>
-<li><code>hcl</code> (Hair Color) - a <code>#</code> followed by exactly six characters <code>0</code>-<code>9</code> or <code>a</code>-<code>f</code>.</li>
-<li><code>ecl</code> (Eye Color) - exactly one of: <code>amb</code> <code>blu</code> <code>brn</code> <code>gry</code> <code>grn</code> <code>hzl</code> <code>oth</code>.</li>
-<li><code>pid</code> (Passport ID) - a nine-digit number, including leading zeroes.</li>
-<li><code>cid</code> (Country ID) - ignored, missing or not.</li>
-</ul>
-<p>Your job is to count the passports where all required fields are both <em>present</em> and <em>valid</em> according to the above rules. Here are some example values:</p>
-<pre><code>byr valid:   2002
-byr invalid: 2003
