「ONLY YOURS」は FontVibe AI で作成した彼への文字エフェクトです。縁にステッチの入ったコニャック色のレザーで包んだ太い大文字。暗い木の机の上で温かな琥珀色の光を受け、横にはウイスキーグラス。

Dark masculine prestige atmosphere — backgrounds of deep navy, forest green, aged charcoal, and warm black. A single warm amber key light from upper-right at 35–45 degrees rakes low across the scene, catching every surface relief in sharp definition and casting directional shadows toward the lower-left. Cool blue-grey ambient fill from upper-left creates dimensional depth and secondary shadow detail. Background scene textures stay subordinate: walnut wood grain, aged slate, dark velvet, hand-laid cotton paper — present at edges and corners, never competing with the primary subject. The tonal palette: cognac amber, antique brass, deep burgundy, muted gold — never cold, never pastel. The visual grammar of premium spirits labels, heraldic gift seals, engraved plaques, and heirloom objects made to last. When no specific surface material is defined by the font: default lighting — warm amber key from upper-right at 40 degrees, cool blue-grey ambient fill from upper-left, near-black background with a faint warm amber glow at depth. Overhead flat lay, square 1:1, near-black velvet surface. Center: the 'ONLY YOURS' gold card face up — antique gold letterforms and laurel wreath glowing in warm candlelight. Arranged around it: two dried deep-red rose stems softly splayed, a small gold wax seal stamp at one corner, a folded dark navy envelope partially visible at the lower edge. Warm amber candlelight from lower-right, everything else in gentle shadow. Deep romantic Valentine's atmosphere — intimate, permanent, for him.
