D019: Visual richness overhaul

Context: The English site shipped text-led with images deferred; the audit + Saif found it "boring / cheap / off", all text on near-black, no product screenshots, no icons, no App Store/Play Store badges, dead scroll space, empty-looking graph/analytics, and (worst) live N stats + [TODO] placeholders in case-study Outcomes.

Decision, add real visual richness (keeping the Stone base + the strong typography/i18n/engineering):

• Imagery everywhere: real screenshots of Saif's live web projects; device-frame mockups + official App Store / Play Store badges for the apps; product logos; tech-stack icons; section iconography.
• Kill all visible placeholders, no N, no [TODO]; real metrics or honest qualitative copy.
• Case studies → scrollytelling (sticky device frame + narrative + before/after) not walls of text; next-project nav.
• Graph: typed nodes (icon + tone + legend), readable labels (hover/zoom), reliable drag, click-to-focus; fix blank homepage teaser canvas.
• Analytics + empty/loading + AI-error states look designed (skeletons, styled error card w/ mailto).
• Motion: staggered reveals, magnetic hover, page transitions; FIX the scroll-jump on Work-card hover.

Colour: stay on the Stone base (light theme is a strength) + one restrained accent for emphasis/graph focus, richness comes from imagery/icons/motion, NOT a generic saturated palette (D011 - Colour Direction Stone; see the design-taste memory). A curated muted-editorial accent palette is optional pending Saif.

Why: "minimal" for Saif still means visually rich + impressive; sparse text read as unfinished. This makes the site walk its own "polish the states nobody screenshots" talk. Partially revisits D003 - Visual Restraint and One WebGL Moment (restraint was over-applied). Built in Phase 7 - Visual and IA Overhaul.
