    1. By default, <details> toggles its content via a discrete state change. To animate this, use allow-discrete to keep the content visible during the exit animation, and interpolate-size to smoothly animate the height to auto.
    2. Type scale (container-aware + zoom-safe via rem bounds).

      They’re design heuristics, not standards. Typically chosen like this:
      1. Minimums (20px / 16px)
          Based on comfortable mobile spacing
          ~16px is a common base unit (1rem)
          20px gives a bit more breathing room vertically
      2. Fluid values (8vh / 5vw)
          Chosen by feel:
            vh → vertical rhythm (hero spacing, sections)
            vw → horizontal gutters
            5–8% is a common “safe” responsive range
      3. Maximums (100px / 40px)
          Prevent layouts from feeling too airy on large monitors
          Keeps content visually grouped
