浓缩咖啡萃取流动特写

一张商业浓缩咖啡机粉碗出液口的电影感微距静帧：浓厚蜂蜜质感的双份浓缩以稳定虎纹流注入预热小白色陶瓷咖啡杯。90mm 微距镜头 f/2.8 侧面平视出液口。下方暖色 LED 灯带斜向打亮液体下落过程中的琥珀金油脂大理石纹。杯中油脂呈红棕虎纹，杯沿隐约蒸汽，粉碗把手为拉丝不锈钢。背景深色咖啡机机身虚化。锈红油脂、蜂蜜琥珀、拉丝银、近黑，精准手工匠心的静谧紧张氛围。

A cinematic macro still of a commercial espresso machine portafilter spout with a rich, honey-thick double espresso shot flowing in a steady tiger-stripe stream into a small pre-warmed white ceramic demitasse. The camera is at 90mm macro, side-on at spout height, f/2.8. A directional under-cabinet LED strip provides warm raking light from below, illuminating the amber-gold crema marbling as the liquid threads downward. The crema surface in the cup shows a reddish-tiger marble pattern. Steam curls faintly from the cup rim. The portafilter handle is brushed stainless steel, partially in frame right. Background blurred dark espresso-machine housing. Color palette: rust-red crema, honey amber, brushed silver, near-black. Mood: precise, artisanal, quietly intense.
