feat: plakat redesign phase 1 (tokens, fonts, poster hero, header)

- New design tokens: signal red, ink and paper as RGB channels; ink and paper swap roles in dark mode so every component inverts cleanly - Fonts via next/font: Bricolage Grotesque (with wdth/opsz axes), Geist, Geist Mono; drop Inter and Playfair - Poster hero: kicker, giant DK0 wordmark that reacts to pointer distance (weight and width through a damped spring, desktop only, off for reduced motion), claim as h1, intro with thesis countdown, marquee strip - Header in poster style: transparent over the red hero, paper strip with ink rule when scrolled or on subpages; drawer menu restyled - Remove wavy SVG separators, CSS shader gradient, background blobs and unused providers that caused the pink/purple bands between sections - Drop the global p/span/div color override so colors inherit properly - New hero texts in de/en, tests and i18n key check updated Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
