漫画风格：音箱触电场景

A black-and-white manga comic panel in a dramatic shonen gag style, showing {argument name="band name on shirts" default="結束バンド"} girls from a high school rock band getting shocked by an overloaded guitar amp during practice. The composition is a single wide panel with 4 girls arranged around a large amplifier in the foreground center, crackling with electricity, smoke, sparks, glowing energy, and jagged lightning bolts wrapping around the scene. Use screentone shading, halftone textures, bold inked outlines, speed-line energy, exaggerated shocked expressions, and chaotic comedy timing. On the far left, 1 partially obscured girl is seated, her face mostly hidden behind a tall rectangular narration box; she wears a dark band T-shirt and dark pants, with one arm bent upward in surprise. Near left-center, 1 girl with long light hair and straight bangs, wearing a dark band T-shirt and a large bow at the collar, stares with spiral eyes and a panicked open mouth, holding one finger up near her lips as if frozen in confusion. Near right-center, 1 shorter girl with messy medium-length dark hair and spiral eyes recoils with both hands raised to her mouth, also wearing a dark band T-shirt. On the far right, 1 long-haired girl in a light zip-up track jacket and skirt sits rigidly with knees together, eyes wide and spiraled, mouth agape, sweat on her face, leaning back in alarm. The amplifier dominates the lower middle, seen front-on with a row of exactly 8 control knobs, a cable plugged into the left side, a cable plugged into the right side, and a small power switch area on the right; bright electrical arcs erupt from the top panel. Include exactly 4 speech or narration text areas: a tall narration box on the upper left reading {argument name="left narration" default="until that day at practice, when the amp overloaded"}, a jagged speech balloon near the lower left reading {argument name="lower left exclamation" default="IT'S ELEC-TRIFIED!"}, a large balloon above the left-center girl reading {argument name="center scream" default="GYAAH!"}, and a large balloon on the upper right reading {argument name="right reaction" default="WHAT THE—?!"}. Also add 1 stylized sound effect near the top center-right reading "ZAP!" with bold Japanese-style impact lettering beside it. Background should be mostly abstract manga effects: dense screentone gradients, electric aura, smoke plumes, and impact bursts rather than a detailed room. Tone: comedic body-swap accident setup, intense but playful, classic manga parody panel.
