TITLE: Brush & Ink — Calligraphy Pad FILE: 075-calligraphy-pad.html === PROMPT (exact prompt used) === Build "Brush & Ink — Calligraphy Pad". A sheet of rice paper (#f5f0e1 with visible fibres and an optional faint grid of practice squares) on a dark wood desk (#2b1d14), with an inkstone and a brush illustrated at the side. Drawing produces convincing brush strokes: width responds to speed (slow = thick, fast = thin) and to pointer pressure when available; ink runs out over a long stroke, producing dry-brush "flying white" texture; stroke ends taper; ink bleeds slightly into the paper (a subtle blurred halo). Ink colours: sumi black, diluted grey and vermillion. Tools: brush size, ink wetness, undo, clear (the paper slides away and a fresh sheet slides in), a red seal stamp you can place (SVG seal with generated square characters), and PNG download. Include a "trace" mode that shows faint model strokes of a simple character (e.g. 永) to practise over. Typography: small, elegant serif labels with vertical-text accents. SHARED REQUIREMENTS (apply to every page in this 100-page collection): 1. One standalone HTML5 file. All CSS inline in
