Joyful celebration light field — backgrounds drawn from deep midnight navy, velvety near-black, rich warm charcoal, and dark burgundy with subtle tonal warmth; every background holds visual weight and depth, never flat or pure white. Key light arrives from directly overhead at 85–90 degrees as a broad soft high-intensity wash — the quality of a grand celebration spotlight — landing evenly across the composition with minimal directional shadow. Secondary fill from both flanks simultaneously at 40–45 degrees at 50% key intensity eliminates shadow zones while preserving full three-dimensional volume. Atmospheric particles inhabit the mid-ground at low-medium density: fine confetti paper fragments, drifting sparkle glints, floating botanical petal shapes — their scale and density shift with direction energy. Color temperature shifts by context: cool electric spectrum (magenta, cyan, lime-green) deepens the darkness for neon party directions; warm rose-amber spectrum softens the background for floral calligraphy directions; full-saturation rainbow vivid for balloon party directions. Background depth is reinforced by a subtle corner vignette; the central field brightens toward maximum luminosity at the text zone. Letter surface material and texture are defined entirely by each font's own prompt_core — this style provides only the celebration light field and atmospheric environment. When no specific direction or font material is active: deep midnight navy background, overhead broad soft white key light at 90 degrees, fine multicolor confetti scatter at 10% scene density, equal-intensity soft fills from both flanks, no floor surface, no props.
