Chronology of Architecture Art Nouveau Curves Infographic

Card grid infographic titled "Art Nouveau Curves". 8 uniform cards in a clean grid, designed as a timeline of architectural movements interpreted through Art Nouveau curves, in a vintage textbook plate style with an Art Deco gold and black palette. Each card contains a clear central architectural icon/diagram with architecturally accurate proportions and example details, a name in English, and a one-line description in English. Include cards such as Early Influences, Proto–Art Nouveau, Mature Art Nouveau, Regional Variants, Structural Ornament, Floral Ironwork, Whiplash Line, and Transition to Art Deco. Show elegant chronological flow across the grid while keeping each card uniform. Use refined engraved poster aesthetics, decorative borders, gold linework on deep black, subtle aged-paper texture, precise facade silhouettes, window shapes, arches, iron railings, organic tracery, and ornamental motifs characteristic of Art Nouveau. Emphasize architecturally accurate examples, especially sinuous whiplash curves, floral geometry, asymmetrical facades, and integrated ornament. Editorial reference-poster illustration.

Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no real brand logos, no watermarks Architecturally accurate examples and proportions.
