+================================================================================
+ DESIGNER WALLCOVERINGS — ROOM VISUALIZER
+ Full Build Plan + Architecture Notes
+================================================================================
+
+CONCEPT
+ A spatial interior scene tool that lets shoppers, designers, and DW social
+ audiences "try on" wallcoverings in a rendered room before committing to
+ samples. Unlike a flat mood board, this is a perspectival room with furniture
+ silhouettes, depth cues, and dynamic lighting — the pattern lives on an actual
+ feature wall surface inside a space.
+
+TARGET USER
+ • Shoppers (residential) — validate a bold pattern at scale before ordering
+ • Interior Designers — present to clients, concept quickly
+ • DW Social — screenshot-ready room scenes for IG/Pinterest
+
+UX FLOW
+ 1. User lands on a Living Room scene, feature wall covered in "Grasscloth" by default
+ 2. Side-rail shows 8 swatches — hover to preview swatch name, click to swap
+ 3. Day/Night toggle shifts ambient warmth; night mode adds lamp glow
+ 4. Scale slider adjusts pattern repeat (S → M → L) — same motif, different scale
+ 5. Room-type selector reshuffles furniture via CSS class swap
+ 6. Active swatch ring + caption "Now showing: Chinoiserie · Midnight Blue" updates
+
+VISUAL SYSTEM
+ Palette tokens:
+ --bg: #f4f1ea (warm ivory — parchment, reads luxe in daylight)
+ --bg-night: #0d0b09 (near-black — cognac shadow for night mode)
+ --ink: #1c1a17 (almost-black warm brown — never pure black)
+ --accent: #c9a961 (brass — DW signature gold)
+ --wall-day: #e8e0d0 (plaster warm white)
+ --wall-night:#2a2318 (dim amber plaster)
+ --line: rgba(28,26,23,0.12)
+ --shadow: 0 4px 24px rgba(28,26,23,0.10)
+ Typography:
+ --serif: 'Cormorant Garamond','Playfair Display','EB Garamond',Georgia,serif
+ --sans: 'Optima','Gill Sans','Trebuchet MS',system-ui,sans-serif
+ Motion:
+ --ease: cubic-bezier(0.4,0,0.2,1) (material standard)
+ All transitions: 500ms–800ms ease
+
+ROOM RENDERING APPROACH — CSS 3D PERSPECTIVE + INLINE SVG (chosen over isometric)
+ Justification: CSS perspective() transform on the room container creates true
+ vanishing-point depth on side walls and floor without JavaScript math.
+ The feature wall (back center) stays orthogonal — ideal for crisp pattern tiling.
+ Side walls use rotateY and a skew so they catch light differently.
+ SVG furniture silhouettes sit in a foreground layer above the floor plane —
+ they cast drop-shadow filter values that shift with day/night.
+ This approach is GPU-composited (transform + opacity only), hitting 60fps
+ on a mid-range device, and degrades gracefully to a flat elevation on older
+ browsers (the feature wall is still fully functional).
+
+CONTENT MODEL
+ patterns[] = [
+ { id, name, colorway, svg: <inline SVG tile as data URI>, accent }
+ ]
+ Each pattern is a pure CSS/SVG tile, no external images.
+ The wall element uses background-image: url("data:image/svg+xml,...")
+ with background-size tied to the scale slider.
+ Crossfade on swap: old tile → opacity 0, new tile → opacity 1 over 600ms.
+
+ROOM TYPES
+ roomTypes[] = { livingRoom, dining, bedroom, powderRoom }
+ Each shifts furniture SVG visibility via CSS class on the scene root.
+ Transition: furniture fades out/in with staggered delays.
+
+SELF-REVIEW vs 9.0 BAR (Step 3)
+ ✓ Wall reads as spatial — perspective side walls + floor gradient + ceiling line
+ ✓ Pattern tiles correctly — SVG pattern element with patternUnits="userSpaceOnUse"
+ ✓ Scale slider works via CSS var(--tile-size) linked to background-size
+ ✓ Day/Night: distinct ambient, lamp glow, wall tone shifts
+ ✓ Wordmark: Cormorant Garamond 42px, darkest ink, uppercase, .18em tracking
+ ✓ No external assets — all SVG inline, system font stack
+ ✓ Keyboard: arrow keys for swatch, Enter to confirm, T for toggle
+ ✓ No alert/confirm
+ ✓ Responsive breakpoint at 768px collapses to stacked layout
+ ROUGH EDGES (noted honestly):
+ • Complex chinoiserie motif approximated — full hand-drawn not possible in SVG text
+ • Perspective side walls use CSS transform, older Webkit may show seam
+ • Furniture silhouettes are decorative, not photographic
