               "Style is wide-shape silhouettes with flat solid color fills, clean cut edges, simple geometric forms. "
               "Strict palette: dark forest green #1f4b37, sage green #4a7c4e, yellow-mustard #e8c547, beige #e8e4d8, white highlights, optional small red-orange accent #c97b5a. "
               "WHEN the dish contains an EGG with visible yolk, the yolk MUST be bright yellow #f5c63a — never green or sage. "
               "Plate is round, dark forest-green rim, viewed top-down, filling about 75% of the square frame. "

Next to it: a yellow lemon wedge as a flat triangular shape with yellow-mustard #e8c547 fill, a small sprig of sage-green parsley.",
    'sachertorte': "On the plate: a single round slice of a dark chocolate cake (Sachertorte), viewed top-down or slightly tilted — the slice shape is a wedge with dark forest-green chocolate glaze on top and outside, beige sponge inside, one thin orange-mustard #e8c547 stripe of apricot jam in the middle as a horizontal line. Beside: a small white-beige dollop of whipped cream.",
    'apfelstrudel': "On the plate: a thick diagonal slice of apple strudel, beige rolled pastry shape with thin spiral lines indicating the rolled dough, golden-mustard #e8c547 apple filling visible at the cut end. Light beige powdered sugar dust on top. A small sprig of sage-green mint as garnish.",
    'topfengolatschen': "On the plate: 2 square pastry pockets (Topfengolatschen) — beige #e8e4d8 golden pastry with 4 corners folded into the center showing white creamy filling in the middle. Light dust of powdered sugar on top (as small white dots).",
    'bayerische-brezel': "On the plate: a large brown-mahogany Bavarian pretzel (Brezel) as a flat 3-loop knot shape filling most of the plate, dark brown-beige #a87253 color with a sprinkle of large white salt crystals on top. Next to it: a small beige bowl with white-cream Obatzda cheese spread, topped with sage-green chive flecks and red-orange paprika sprinkle.",
    'schwaebische-maultaschen': "In the bowl: 3-4 large square dumplings (Maultaschen) — beige pasta squares filled visible — placed in a clear golden #e8c547 broth. The dumpling tops show a sage-green spinach hint through the dough. A few golden roasted onion strips beige-brown on top.",
    'rheinischer-sauerbraten': "On the plate: a stack of 3-4 thin slices of dark brown #a87253 braised beef (Sauerbraten), glazed with shiny dark sauce. Around: a small dollop of beige potato dumpling (Klöße), a few dark purple-red braised red cabbage strips (use forest-green and yellow-mustard mix for cabbage tone), 3 dark raisins as small dots in the sauce.",
    'schwarzwaelder-kirschtorte': "On the plate: a single wedge slice of a layered cake (Schwarzwälder Kirschtorte). Three layers visible from the side: dark forest-green chocolate sponge alternating with white whipped cream, red cherries (use red-orange #c97b5a) scattered in the middle layer. On top: a thick swirl of white cream with a single red cherry crown. Dark chocolate shavings as forest-green small slivers around.",
    'schweizer-kaesefondue': "Top-down view of a round shallow caquelon (fondue pot) in dark forest-green ceramic. Inside: smooth creamy golden-beige #e8c547 melted cheese filling the whole bowl, with two fondue forks sticking out at angles — fork handles dark forest-green. Beside the pot on the table: a small pile of beige bread cubes (4-5 cubes shown as flat square shapes).",
    'zuercher-geschnetzeltes': "On the plate, split visually in two: LEFT side a round golden-brown #e8c547 rösti (potato pancake) as a flat disc, very lightly textured. RIGHT side: a small mound of thin brown-beige #a87253 meat strips in cream sauce, with a few sage-green parsley flecks and dark grey-brown mushroom slices visible."
