+/**
+ * A Web Awesome form control is at least the app's 44px touch floor.
+ *
+ * #56 named 44px and #186 found nothing but the transport had reached
+ * it. Web Awesome's form controls are the part of Settings this app
+ * does not draw: measured on the reference device (TLP301, 424x439),
+ * `wa-input`'s control is **204x20** and `wa-button` **185x21** — the
+ * shortest controls on the page, and the only ones whose height is
+ * decided inside somebody else's shadow root.
+ *
+ * `--wa-form-control-height` is that decision, and it is the library's
+ * own theming variable rather than a part or an internal — the default
+ * theme sets it at `:root` and every control that has a height reads
+ * it (button, input, select, radio). So this is `wa-slider-label`'s
+ * better half: the API first, and no reach into a shadow root at all.
+ *
+ * Three things about it are load-bearing.
+ *
+ * **A custom property inherits through a shadow boundary**, which is
+ * what lets a `:host` declaration reach a `wa-input` the host renders.
+ * That is also why it is a stylesheet a component adopts rather than a
+ * `:root` rule in `index.css`: a `:root` rule would cover every wa
+ * control in the app in one line and be invisible to the component
+ * tier, which renders a component and no page stylesheet. Here the
+ * floor is measurable where it is applied.
+ *
+ * **It is a flat 44px rather than a floor over the library's own
+ * expression.** The default is `round(calc(2 * padding-block + 1em *
+ * line-height), 1px)` — em-based, so `size="small"` is what produced
+ * the 20px above — and a `max(44px, …)` would have to restate that
+ * formula here, which is a copy of somebody else's arithmetic that
+ * goes stale silently. A flat value is safe because this app uses
+ * exactly two sizes, `small` and the default, and both are under the
+ * floor; a `size="large"` added later would be pinned down to 44 and
+ * should take that as the prompt to revisit this.
+ *
+ * **Only the height is pinned.** The font size still comes from
+ * `size="small"`, so a control grows its hit area without growing its
+ * visual weight — which is what #186's Direction asks for and what the
+ * page header's second pass had to be corrected to do.

+ * screen. Settings is the other half and is much the larger one: swept
+ * on the reference device (TLP301, 424x439) with all eleven
+ * `config-section`s expanded, **120 controls** were under the floor,
+ * not the 93 the issue's first table implies, and `config-field` — the
+ * row shape the issue names — is eight of them. The bulk is behind the
+ * disclosures:
+ *
+ * | control | size | count |
+ * |---|---|---|
+ * | `.column-arrow-btn` | **16x14** | 36 |
+ * | `.column-toggle` | 16x16 | 29 |
+ * | `shortcut-capture` button | 80x**25** | 26 |
+ * | download format checkbox | 16x16 | 8 |
+ * | `config-field` select | 335x**30** | 7 |
+ * | `wa-input` / `wa-button` | 204x**20**, 185x**21** | 6 |
+ * | `library-filter` select | 120x**32** | 1 |
+ * | `.overflow-btn` | 31x31 | 1 |
+ *
+ * **This tier can measure it, unlike #187's seek bar**, for the reason
+ * the header pass gives: the controls are real elements and the rules
+ * are min-sizes, so a real Chromium rendering a real component gives
+ * the actual answer at any width. And unlike the header there is no
+ * overflow fit on this page, so nothing here needs the negative-margin
+ * treatment — height is free and the two square controls can simply be
+ * square.
+ *
+ * **What the sweep cannot see is written down here as a test rather
+ * than as a comment**, because it is the trap this whole issue keeps
+ * setting. Two controls are invisible to a walk of `button, select,
+ * input`: `config-field`'s toggle, whose `<input>` is
+ * `opacity: 0; width: 0; height: 0` so the thing a finger hits is the
+ * `<label>` around it (34x19, smaller than anything in either of the
