「Happy 65th, Dad You Fixed Everything We Broke」は FontVibe AI で作成したバースデーの文字エフェクトです。白フチのくっきりした虹色ストライプの丸い大文字。紙吹雪と風船の束に囲まれ、ピンクからターコイズへの鮮やかなパーティー背景。

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. A dad's garage-workshop birthday setup, vertical 9:16 portrait, slight overhead angle. Wooden workbench covered with a checkered cloth — birthday cake with '65' candles lit at center, warm candlelight washing amber glow across the pegboard of well-worn tools behind. Wrenches, a hammer, screwdrivers organized on the wall — a lifetime of fixing things on display. Gold and navy birthday streamers loosely draped between the tools, imperfect and heartfelt. The birthday card propped upright at the near workbench edge, face toward camera — 'Happy 65th, Dad · You Fixed Everything We Broke' in bouncy bold script clearly readable. Warm overhead workshop lamp. The whole setup assembled by his kids — real, not staged.
