照片级真实感剪影日落合成，宽幅16:9全景构图，电影级，超精细。边缘到边缘，无画框，无边框。

Photorealistic silhouette sunset composite, wide 16:9 panoramic composition, cinematic, ultra-detailed. Edge to edge, no frame, no border.

SKY: the upper half is a furnace of amber, apricot and burnt gold, deepest at the horizon, cooling to smoky blue-grey at the very top. Long streaky cirrus clouds sweep diagonally across it, undersides lit gold, edges trailing thin warm wisps.

SUN: one huge perfectly round pale white-hot sun disc sits exactly at the centre of the frame just above the treeline, its rim glowing and bleeding a soft warm halo into the surrounding orange.

TREE: dead centre, in front of the sun, a single massive spreading broadleaf tree in pure black silhouette — a thick trunk flaring at the base into a rounded knoll, and a vast dense canopy of fine branch tracery and leaf clusters spreading wide and symmetrical, its edges softly dissolving into the glow.

CITY: flanking the tree, a dense skyline of black skyscraper silhouettes stands along a low ridge of rooftops. Left, a tall stepped tower with twin thin antennae, ringed by shorter blocks. Right, three dark high-rises of graduated height, one carrying a slender spire. The buildings never overlap the tree and never cross the sun.

WATER: the entire lower third is a frozen lake surface, not smooth water — a turbulent marbled expanse of glacial ice and flowed stone, banded in chalky white, sea-green, slate grey and warm tan in long swirling veins.

REFLECTION: sky, sun, tree and skyline all mirror downward into that marbled surface, broken and stretched by the ice grain. The reflected sun lies as a broad soft gold field beneath the trunk, the reflected tree spreads as a dark root-mass of branching veins below it, and the reflected towers hang as vertical dark bars, all smeared by the swirling white and green stone.

PALETTE: pure black, apricot, amber gold, burnt orange, smoky grey, chalk white, glacier green, tan. Sharp silhouette edges against soft glow, high dynamic range, clean and unmarked.
