; ===== HATCHING TECHNIQUE NOTES =====
; - Background: Vertical lines with varying density for tonal gradient
; - Moon: Concentric circles with radial hatching for luminous effect
; - Trees: Crosshatching at 45° angles, density varies by tree
; - Foliage: Dense crosshatching for dark areas, lighter for mid-tones
; - Water: Horizontal lines with occasional verticals for surface texture
; - Rocks: Stippling technique with short random marks
; - Path: Horizontal texture with directional marks
; - Silhouettes: Solid fill using closely spaced parallel lines
;
; Total estimated plot time: 45-60 minutes on large format plotter
; Pen changes recommended: Fine tip (0.3mm) for detail, medium (0.5mm) for fills
