A Career Change Told in Flat Illustration

integrated_multimodal_description: Create a complete 15-second Japanese flat-illustration commercial in a vertical 9:16 composition for a fictional career-change agency called トビラ. Use friendly 2D flat-vector picture-book illustration: thick, even, near-black outlines of consistent weight, flat solid color fills, no shading, simple dot eyes and small curved mouths, restrained cutout animation, and a light paper grain over the flat color fields. Use a compact palette of warm off-white, muted slate blue, coral red, golden yellow and fresh mint green, with near-black outlines. Background color changes mark the chapters. Because the frame is vertical, elements stack from top to bottom and are never laid out in a horizontal row. No photorealism, no 3D rendering, no gradients, no drop shadows, no browser interface, no screen-recording artifacts, and no player controls. [Shot 1] Begin on a warm off-white background. A young office worker with short black hair, a white shirt, navy trousers and one round blush spot on each cheek sits side-on at a small desk with an open laptop. Their hands stop moving on the keyboard and come to rest. The Japanese caption "このままでいい？" then appears across the upper area, arriving one character at a time. A round wall clock above them turns its hand a full circle. [Shot 2] At 00:02.500, a muted slate-blue field wipes across the frame. The same worker sits smaller in the centre. Three round white speech bubbles pop in one at a time around them, reading "給料", then "時間", then "やりがい". The bubbles crowd inward toward the worker, and their eyebrows lower as their shoulders drop. [Shot 3] At 00:05.000, a coral-red field wipes across the frame. The worker holds up a smartphone and plain white cards, each with two short grey lines on it, pour out of its screen one after another and pile up until they fill the frame. Their free hand reaches toward the cards and stops halfway. The caption "動けない" assembles in two stages in large near-black type. [Shot 4] At 00:07.500, a golden-yellow field wipes across the frame and the picture brightens. A friendly guide in a golden-yellow cardigan with round glasses and a document folder pops in from the lower right. Three white outlined cards then stack up one at a time from top to bottom, reading "仕事を探す", "書類を整える" and "日程を決める". Small yellow plus signs appear in the gaps between the stacked cards. [Shot 5] At 00:10.000, a fresh mint-green field wipes across the frame. The three stacked cards connect into a single top-to-bottom flow with simple arrows between them. A handshake symbol appears below the lowest card. The worker stands beside it empty-handed, the corners of their mouth lifting and their shoulders rising. [Shot 6] At 00:12.500, the background settles back to warm off-white with generous empty space. The caption "まずは、話すだけ。" appears in near-black type in the upper area. A simple door mark and the brand name "トビラ" then appear together in the centre. The door mark swings open and a wedge of golden-yellow light spreads out from behind it, holding cleanly until exactly 15.000 seconds. overall_soundscape: A steady keyboard tapping stops abruptly at the start, leaving a quiet clock tick. Paper-like pops mark each speech bubble and each caption, and a run of riffling card sounds swells and then cuts off sharply. Short restrained whooshes carry the color-field wipes, small UI clicks land as each card stacks into place, and a soft confirmation chime accompanies the handshake. A light wooden door sound opens the final shot. No dialogue. non_diegetic_music: Generate an original 15-second friendly Japanese commercial jingle using light marimba, soft plucked synth, gentle hand percussion and warm sustained chords at a moderate tempo. Begin sparse and hesitant over the off-white opening, sink lower and slower over the blue section, tighten and grow restless over the coral section, open up bright and warm as the yellow section arrives, keep that warmth moving through the mint section, and resolve with one clean final chord at exactly 15.000 seconds.
