--h-space-size |
Width of <h-space> / <h-s>. |

Styling & Behavior
- Both elements inherit
color, background-color, and font.
- Horizontal box: width =
size, height = thickness (default 0).
- Vertical box: height =
size; add inline attribute for inline layout.
- Inner text is accepted as input but not rendered (hidden by a shadow
<slot>).
- Changing attributes or inner text at runtime updates the gap (MutationObserver).
- FOUC guard auto-injected via
:not(:defined) hides raw values until upgrade.
