## #263: Time display — diegetic time readout on the player's neural insert (D-013, D-031).
## Shows station local time (HH:MM), day phase, and day number.
## Lives on InsertOverlay (CanvasLayer 10) per D-051 diegetic insert principle.
## Draw-based for implant visual aesthetic. Updated via update_from_state() from main.gd.
##
## Placeholder layout — position and style will be refined when #314 wireframe lands.
