/* Entry 025 — The echo
   Series: Last Screens.
   Scene art direction: a bedroom at 2 a.m., near-black, the room dissolved to warm
   shadow except one low amber lamp-pool upper-left. A single frosted message thread
   floats in the dark. One accent: the COOL screen-blue of the messages that come
   *back* — her replies arrive the wrong temperature, tender in content, cold in colour.
   Two voices: Cormorant Garamond italic for her returning voice (the soul), Sora for
   the machine chrome and your own typing. Distinct from 017's warm-amber last-thread. */
