宣传风格修学旅行日程海报

Using REFERENCE_0 as the source document, transform the plain school trip timetable into a dramatic vintage socialist-propaganda style poster while preserving the original 2-night/3-day schedule contents and Japanese itinerary structure. Replace the clean worksheet layout with aged beige paper, heavy black ink, distressed halftone texture, bold red-and-black typography, diagonal banners, and revolutionary poster composition. Add a large top headline reading {argument name="headline text" default="修学旅行"} with the subheading {argument name="subheading text" default="タイムスケジュール"}, plus a black banner for {argument name="region label" default="関西方面　2泊3日"}. Split the itinerary into exactly 3 visible schedule panels labeled DAY 1 京都, DAY 2 奈良・大阪, and DAY 3 大阪, keeping the times and activities from the reference legible in each panel. Add propaganda-style supporting imagery not present in the reference: crowds of uniformed students/workers, raised fists, red flags, industrial smokestacks, dramatic city silhouettes, castle illustrations, and a red fist emblem in a star at the lower right. Add exactly 3 slogan areas: a red speech-banner at the upper right reading {argument name="top slogan" default="学ぶことは変えること！団結する者が、未来をつくる！われらの力で、歴史をすすめよ！"}, a large lower-left slogan block reading {argument name="bottom slogan" default="労働する者は団結せよ！学び、考え、行動せよ！未来はわれらの手にある！"}, and a bottom notice box titled 注意事項 with concise school-trip rules. Make the poster look like a scanned, worn, high-contrast risograph/woodblock propaganda print, with red as the dominant accent color and black borders separating the 3 day panels.
