   Boundary Lines — shared stylesheet
   Design concept: a surveyor's field map. Deep ink background, graph-paper
   grid, dashed property-line dividers, amber flag-marker accent, and a
   traverse-line signature that plots the studio's territory (Games / AI
   Tools / Albion Hub) like waypoints on a survey.
