  /* Round 3: the handle is a 52px circle riding the seam's 0-width left edge
     (calc(var(--t,0) * 100%)); at t=0/t=1 that puts the seam flush with the
     viewport edge and half the circle off-screen. The seam LINE may still
     touch the true edges; only the handle's own travel is inset by its half
     width (26px). Since .tx-handle's containing block is .tx-seam (already
     offset by --t), the extra "left" here is the DELTA between the clamped
     absolute position and the seam's own position, not the absolute position
     itself: 0 in the middle of the travel (handle rides the seam exactly),
     and it only pulls the handle inward once the seam gets within 26px of
     either edge. Relies on .tx-stage being full-bleed with the viewport at
     this breakpoint (no side padding), confirmed live at 390px. */
