Glowing Light Spiral Christmas Eve Party

Professional Christmas Eve party invitation, vertical, light-painting night scene. [Colors] Cobalt #12256B to indigo #1B1E4F gradient, electric violet #7B4BD6, cyan #4FD1E8, hot pink #FF5CA8, magenta glow #E24FA1. [Layout] Single centred column: small kicker at the top, two-line title, a tall luminous spiral tree as the hero, then a date block, a venue line and a code at the base. [Typography] Thin elegant sans with wide letter spacing, hairline rules above and below the date, small caps for the venue. [Subject] A Christmas tree drawn as a coiled ribbon of glowing LED light trails with intense pink and violet flares, beside a reindeer silhouette formed from scattered star sparks. [Lighting & mood] Long-exposure glow, deep navy darkness, floating sparks, cinematic and dreamy. [Details] Bokeh orbs, smeared light streaks, faint star clusters, soft blue haze drifting across the lower field. Text: "CHRISTMAS EVE", "INVITATION", "DEC 25".
