/* RoomPrice Monitor design sample (Claude, 2026-10-11), shared by all three pages.
   Keeps the live site's Orbit Blue tokens. Market-position colours follow the program
   (gui.py CALENDAR_STATUS_COLORS): below = cyan, near = blue, above = amber.
   Price movement follows the Email summary: up = amber ▲, down = cyan ▼.
   Purple only ever means "competitor median" (the dotted line in the trend chart). */
