Chalkboard aesthetic — the visual language of artisan hand-lettering on dark board surfaces. COLOR CLIMATE: high-contrast warmth defines the palette. Foreground marks: cream-white to warm ivory as the primary tone, with dusty pastel accents — soft coral, sage, lavender, warm mustard — for secondary decorative elements. Background ground: deep chalkboard green-black or charcoal slate. The dark ground is an active compositional element, not neutral filler. LIGHT ATMOSPHERE: warm overhead ambient at cafe or classroom intensity — the quality of morning light through a cafe window or an evening Edison bulb above a pub specials board. Soft directional quality, revealing surface and dimension without creating harsh contrast. Warm, inviting, crafted. DECORATIVE REGISTER: simple hand-drawn borders of dots, dashes, or double-ruled lines; small illustrative accents (arrows, stars, leaves, dividers); mixed-weight lettering styles on the same surface — all belong to the chalk aesthetic vocabulary and may appear in compositions. When no specific material is defined by the font: default lighting environment — warm overhead ambient, cream-white chalk tones against deep chalkboard green-black board ground, soft and matte in quality. An aged dark slate chalkboard within a wide wooden frame, warm amber overhead light casting gentle warmth across the board surface from above. The wooden frame shows worn patina at the corners. Text: "Happy birthday souliee" stacked as a centered two-line display — "Happy birthday" / "souliee" — "souliee" enlarged and dominant filling 78% of frame width, "Happy birthday" scaled above it. 16:9 widescreen format.
