   /theta slot-machine hero (one-off, /theta only).  Four horizontal
   lanes stacked vertically; each lane is one full line of display
   type.  Lane 0 (top) is blank by construction (the target is only
   three lines long: "This / is / Theta."), so it never spins and
   exists purely to give the head its four-line vertical footprint.
   Lanes 1-3 are spinners: each is a fixed-height window of one line-
   height that clips a vertical "tape" of stacked word rows.  The
   tape's first row is the start word, last row is the target word,
   middle rows are brand-clean fillers.  Tape translates upward to
   bring the target row into the window.  Single translateY per lane,
   easeOutQuint, ~1000ms, ~130ms lane-to-lane stagger.

   The static fallback (.slot-static) renders the final state
   instantly and is the only path shown under prefers-reduced-motion
   or no-JS.  The animated path (.slot-stage) is JS-mounted; when
   present it suppresses the static node.

   Brand-rule notes: the trailing period on "Theta." is the section's
   one Clay accent; no italics in this block; no additional accents.
