  /* `width`/`height` have no effect on a plain `display: inline` element
     per spec — <label> is inline by default, so it silently ignored a
     1px constraint and kept contributing its full text width (~189px) to
     the page's scrollable area. display: block makes a size constraint
     actually apply — and zero (not 1px) because even at 1px, the <input>
     specifically still contributed some residual width to
     document.documentElement.scrollWidth (measured directly), most
     likely its native minimum control size. Zero plus overflow: hidden
     leaves no box for that minimum size to apply to. */

     directly removing the widget and re-measuring: it was single-handedly
     responsible for ~109px of the page's horizontal mobile overflow
     (worse: once ANYTHING forces the layout viewport wider than the
     device width, every other percentage/vw-based measurement on the
     page — even unrelated ones — starts computing against that wider
     viewport too, which is why a misaligned-looking button elsewhere
     turned out to have the exact same root cause). `data-size="flexible"`
     on the widget element (see index.html) is the real fix; this is a
     belt-and-suspenders cap in case that ever fails to apply.
