/* The power glyph is built from real shapes (not the "O" letterform) so its
   two halves can be independently animated. Both halves AND the strike live
   inside one rotated ".power-rotor" so the halves' top/bottom split is drawn
   at the strike's own 45deg axis instead of screen-vertical. Each half is a
   clipped window onto a double-height ring (the standard CSS half-circle
   trick); "erasing" a half means growing its clip-path inward FROM the edge
   that touches the strike, so it visibly shrinks into the strike instead of
   sliding past it into the other half's territory. A separate fill disc
   (behind the rotor) fades in/out to sell the "spinning until opaque" look,
   same mechanism as the About PC logo's .nextos-o-fill. */
