Interactive 3D White House web app showcase

[Note: the creator shared a partial prompt. Wording below is theirs.] GOAL: Build an interactive 3D model of the White House and President's Park in Washington, D.C. MOTION: as a single web app using three.js. Generate everything in code: no 3D model files, no image or texture downloads. Build geometry from code and draw every texture on a canvas or in a shader. It must run smoothly in a desktop browser and look polished enough to record as a showcase video. THE BUILDING (accuracy matters) - The Executive Residence at real proportions: about 168 x 85 ft, eleven window bays across, white painted sandstone, a rusticated ground floor that shows only on the south side (the north lawn sits a storey higher), a full classical entablature, a balustrade with individual balusters around the roof, a low grey hip roof, eight chimneys, and the US flag flying from a pole on the roof. - Windows with six-over-six sashes and architrave surrounds. State Floor windows alternate triangular and segmental pediments; second-floor windows have flat hoods. - The South Portico: a curved bow with six tall Ionic columns (base, shaft with entasis, volute capitals), the Truman Balcony at second-floor level behind the columns, arched openings in the base, and twin curved staircases down to the lawn. - The North Portico: a porte-cochere with Ionic columns, a triangular pediment, and a hanging lantern. - The West Wing with the bowed Oval Office facing the South Lawn, the East Wing, and the colonnades that link them. The West Colonnade borders the Rose Garden; the Jacqueline Kennedy Garden sits on the east side. THE GROUNDS AND SURROUNDINGS - The South Lawn with mown stripes, the oval drive, the South Fountain (circular basin, tall central jet, ring of smaller jets, flower bed around it), the Rose Garden, and flower beds along the south facade. - The North Lawn with its curved drive and fountain, Pennsylvania Avenue as a paved plaza, and the black iron perimeter fence with stone piers. - Lafayette Square with brick walks and the Jackson equestrian statue, St. John's Church, the Eisenhower Executive Office Building (granite, slate mansards), and the Treasury with its Ionic colonnade. - The Ellipse with its ring road, the National Mall with rows of elms, and the Washington Monument with its ring of fifty flags. - City blocks around the park, kept low to respect DC's height limit, with window grids that light up at night. - Hundreds of trees of several species: oaks, elms, magnolias, cedars and cherry blossoms. Leaves sway in the wind. - Washington globe lamp posts, park benches, visitors walking the paths, tourists at the fences, and traffic on the avenues. LIGHT, SEASONS AND LIFE - A physically based sky with sun, soft shadows, image-based lighting, light haze and drifting clouds. - Three light presets that blend smoothly into each other: - Morning - Golden hour - Night: stars, a floodlit facade, warm lit windows, glowing street lamps and lit fountains - Four seasons that blend smoothly: - Spring: cherry blossoms and tulips - Summ
