/* Second Exposure — a visualization of a personal deja vu log.
   Identity: double-exposure photography. Type and key marks carry a faint
   offset ghost twin. Periwinkle = presence (an episode happened).
   Amber = repetition ONLY (calendar echoes, the Interalpen pair, the
   18.7-hour double). Never elsewhere. */
