Vertical Pass on the Stacked Baumkuchen Spire

Full prompt

A vertical 9:16 phone wallpaper photograph capturing a multi-tiered Baumkuchen tower rising like an alpine summit, deliberately composed with generous uncluttered space across the upper third for digital interface clarity. In the lower and middle tiers, a solitary miniature road cyclist stands out of the saddle, pedaling vigorously up an angled spiral ramp cut into the layered golden rings. Fine drifts of sifted confectioner's sugar cling to the knobby bark-like exterior, evoking high-altitude glacial snowdrifts along an arduous mountain pass. Crisp morning side-lighting casts long, slender shadows across the ridged crumb, highlighting the warm amber and pale butter layers of the exposed sponge beneath. The background softly blurs into luminous, soft bakery ambient light above.
