「Once upon a time」は FontVibe AI で作成したカスタムスタイルの文字エフェクトです。

A moonlit medieval scriptorium viewed straight-on, with a broad slab of aged vellum pinned to a dark oak writing desk at the center of the frame. Around its edges: a closed leather-bound codex, a small ceramic ink pot, a goose quill resting diagonally, and several dried oak leaves; keep every prop pushed into the outer margins. Behind the desk, a rough lime-plaster wall recedes into dim blue-black shadow, with a narrow arched window at upper left showing a deep indigo night sky and a small pale moon. One beeswax candle in a brass holder stands far right, casting a soft amber pool across the desk surface and long, diffuse shadows behind the objects. The central vellum area remains clean, pale, and evenly illuminated for maximum legibility. Set the exact text "Once upon a time" as one centered line across the vellum, large and dominant, with generous clear space above, below, and on both sides. No additional writing, captions, seals, decorative borders, or symbols. Fine paper grain, faint deckled vellum edges, shallow depth of field focused precisely on the text, natural candlelight and cool window fill, high-resolution editorial still life.
