   Wave 8 (2026-05-09) — segmented mode toggle for the AI Board
   Assistant left rail. Three pills: AAC / Routine / Lesson. Active
   pill = amber filled (matches brand + the props-panel image-mode
   tabs visual language for cross-surface consistency).

   Sits ABOVE the chat input row so the user picks a mode BEFORE
   typing the topic. ai-rail.js's clarifier question gets skipped
   when a mode is locked, dropping a 2-question chat into a
   1-question chat (just size).

   Standalone file — small, isolated concern.

   LABEL: PILOT-READY. Visual styling only.
