Create a vertical 9:16 vintage Chinese old almanac page for April 18, 2026. Design it like a richly decorated traditional huangli calendar poster with a large central date number 18, Gregorian date information, lunar calendar information, auspicious and inauspicious activity columns, zodiac sign, five-elements notes, deity or direction panels, hexagram-style diagram, time-period table, seasonal-term section, and small historical-today notes. Use red, teal, gold, and aged parchment tones, ornate Chinese borders, crane, lotus, carp, waves, mountains, clouds, plum blossoms, and folk-art decorative motifs. Treat all almanac, lunar date, zodiac, fortune, taboo, and historical details as generated illustrative text that must be reviewed for factual accuracy. Avoid presenting the information as verified advice, avoid real religious authority claims, avoid copied existing almanac designs, avoid private information, avoid unreadable critical text, and avoid low-resolution artifacts.
