-<h2 id="overview">Overview</h2>
-
-<p>This is my fork of Domsson’s beautiful <a href="https://github.com/domsson/fakesteak" class="external" target="_blank" rel="noopener noreferrer">Fakesteak</a>. While going through his code, I
-wondered what it would take to faithfully recreate the original Matrix from the
-first movie without sacrificing its minimalism.</p>
-
-<p>My implementation supports:</p>
-
-<ul>
-  <li>Unicode characters.</li>
-  <li>24-bit RGB colors (truecolor).</li>
-  <li>Glitches in the matrix.</li>
-  <li>Ghosting effect of old monochrome CRT displays.</li>
-  <li>Closely resembles the Matrix seen in the background during Neo and Cypher’s
-conversation.</li>
-</ul>
-
-<p>With no dependencies, compilation is trivial:</p>
-
-<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>$ cc -O3 main.c -o matrix
-$ ./matrix
-</code></pre></div></div>
-
-<h2 id="how-does-it-work">How does it work?</h2>
-
-<p>The program tracks the state of the terminal, such as code points, background
-and foreground colors, and cursor position, using multiple internal data
-buffers. On each frame, it updates these buffers and repaints the screen using
-ANSI escape codes:</p>
-
-<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>static void term_print(const matrix *mat, size_t row, size_t col)
-{
-    size_t idx;
-    idx = mat_idx(mat, row, col);
-    wprintf(L"\x1b[%d;%dH\x1b[38;2;%d;%d;%dm%lc",
-        row, col,
-        mat-&gt;rgb[idx].color[R],
-        mat-&gt;rgb[idx].color[G],
-        mat-&gt;rgb[idx].color[B],
-        mat-&gt;code[idx]);
-}
-</code></pre></div></div>
-
-<p>The ghosting effect is achieved by carefully scaling the RGB
-channels before mixing them:</p>
-
-<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>static void mat_shade(matrix *mat, size_t row, size_t col) 
-{
-    unsigned char *color;
-    color = mat-&gt;rgb[mat_idx(mat, row, col)].color;
-    color[R] = color[R] - (color[R] - COLOR_BG_RED) / 2;
-    color[G] = color[G] - (color[G] - COLOR_BG_GRN) / 2;
-    color[B] = color[B] - (color[B] - COLOR_BG_BLU) / 2;
-}
-</code></pre></div></div>
-
-<p>The ghosting function emulates the dim after glow by gradually transitioning
-each raindrop’s color towards the background color. This approach provides two
-key benefits: straightforward color configuration that integrates naturally
-with (Unix) ricing and high-fidelity recreation of the Matrix aesthetic.</p>
-
-<h2 id="customization">Customization</h2>
-
-<p>While you can alter almost every aspect, including speed, glitch frequency, and
-rain density, the most common customizations are the color scheme and character
-set.</p>
-
-<p>There are three color settings: head, tail, and background. You can configure
-them using <code class="language-plaintext highlighter-rouge">COLOR_*_RED</code>, <code class="language-plaintext highlighter-rouge">COLOR_*_GRN</code>, and <code class="language-plaintext highlighter-rouge">COLOR_*_BLU</code> definitions found in
-main.c.</p>
-
-<p>The <code class="language-plaintext highlighter-rouge">UNICODE_MIN</code> and <code class="language-plaintext highlighter-rouge">UNICODE_MAX</code> values control the Unicode block used. For
-example, setting them to <code class="language-plaintext highlighter-rouge">0x30A1</code> and <code class="language-plaintext highlighter-rouge">0x30F6</code> rains Katakana, if a font that
-supports Katakana is present on the system:</p>
