  <h1>Three marks for a ride recorder</h1>
  <p class="lede">
    Each concept is drawn on Android's <strong>108-unit adaptive-icon canvas</strong>, so
    whichever you pick converts straight to a vector drawable with no redrawing. The dashed
    circle marks the safe zone — anything outside it can be cropped by an OEM mask. The
    small tiles are the real test: a launcher icon is seen at 48px and the status-bar icon
    is a flat 24px silhouette.
  </p>

  <div class="grid">{{CARDS}}</div>

  <div class="foot">
    <h3>What happens after you pick one</h3>
    <p>
      The chosen mark becomes <code>ic_launcher_foreground.xml</code> as a vector drawable,
      paired with <code>#101418</code> as the adaptive background, replacing the placeholder
      compass. Its monochrome variant replaces
      <code>android.R.drawable.ic_menu_compass</code> in the recording notification. Source
      SVGs live in <code>design/logos/</code>; regenerate with
      <code>python3 design/gen_logos.py</code>.
