/* The eight-knob band. Phase 10 §4: the host ALWAYS renders this component and the component @if-gates
   the knobs on its Visible parameter. So the container is permanent and reserves its height whether or
   not the knobs are present — content below the bar never pops on toggle. No collapse machinery, no
   transitions, no glass surface. A plain transparent horizontal flex row of the eight knobs that wraps
   to a second line only if the band is genuinely too narrow.

   min-height reserves one knob-row's worth of space (knob Size=64 + icon caption + gaps + margins) so
   the empty (hidden) state occupies the same vertical box the populated single-row state does. On very
   narrow viewports a populated band may wrap to a second row and exceed this floor — the no-pop
   guarantee is exact for the common single-row (desktop) layout. */
