/* On narrow viewports the negative `margin-left: -0.9em` pushes the `#`
   sign past the left edge of the viewport (anchor x ≈ -11px on a 380px
   viewport), so hover-revealed anchors get clipped. On mobile we drop
   the float + negative margin and absolutely position the anchor at
   the heading's left edge instead, with the heading content shifted
   right via `padding-left`. This way:

   * The `#` stays inside the viewport at all times.
   * The `#` is vertically centered against the first line of the
     heading (`align-items: center`), so the two sit on the same
     optical line instead of the `#` floating above the heading text.
   * The heading text gets the full content width (minus the small
     reserved gutter), so a long heading like "Markdown Features" no
     longer wraps with one orphan word on its own line leaving a big
     empty space at the end of the first line. */

       box-decoration-break: clone alone is not enough in practice: the
       per-fragment borders stack against the next fragment's background
       and the visual gap between fragments collapses, making the right
       border of one line look like the left border of the next (and
       neither looks fully closed). Making the element inline-block
       guarantees each fragment draws its own box with its own four

       `line-height: 1.4`, which pushed the box downward and made the
       framed text look like it was sitting on a lower line than the
       surrounding body text — a small offset, but very noticeable in
       tight running prose like list items and paragraphs. With
