brand: Scirium logo (The Cited Element) and design-token SSOT

Add the official Scirium wordmark production assets and the shared design-token source of truth extracted from the converged landing page.

- Production logo assets (14 files): outlined Fraunces wordmark in color, mono, and reversed SVG; print PNGs at 2700x1000; email-signature PNGs at 270x100; full favicon set (SVG, ICO, 16/32/48/512, apple-touch-icon).
- design-tokens.json (v1.0.0) and design-tokens.css: brand primitives, 20 color tokens per theme, font stacks, shadows, radius and type scale, breakpoints.
- Wordmark integrates theme-adaptive on the live page: ink via currentColor, dot via --highlight, underline via --accent (verified light and dark).
