/* ============================================================================= Abbey – Retro Theme Memphis / 8-bit / 80s computer aesthetic. Loaded only when `Rails.application.config.theme == "retro"`. All declarations are scoped under `.theme-retro` (set on by themes/retro/layouts/application.html.erb) so loading this file in any other context is a no-op. Color/shadow/font/animation TOKENS live in `app/assets/tailwind/application.css` under `@theme`, which makes Tailwind auto-generate the matching utility classes (`bg-memphis-pink`, `shadow-retro-lg`, `dark:text-memphis-mint`, `hover:bg-memphis-pink`, `animate-blink`, `text-[0.62rem]`, etc.) — no hand-rolled `.theme-retro .bg-foo-bar` declarations needed. This file ships: 1. theme-root environmental styles (page bg, drifting confetti backdrop, CRT scanlines, selection color) 2. font-family rebinding inside `.theme-retro` so utilities like `font-sans`, `font-mono`, `font-display` resolve to the retro stack 3. component classes (`.card-retro`, `.btn-retro`, `.tag-retro`, `.h-display`, `.crt-window`, `.marquee`, `.date-sticker`, `.glitch-hover`, `.cursor-blink`) 4. typography for the `.prose-retro` wrapper (h1-h3 with hard text-shadows, wavy-underline links, highlighted , terminal 
 blocks, Memphis tables, dotted SVG 
)

   Font-family rebinding via CSS variable cascade.
   Tailwind generates `.font-sans`, `.font-mono`, `.font-display` as
   `{ font-family: var(--font-sans|mono|display) }`. Redefining those
   variables on `.theme-retro` makes every `font-*` utility inside the
   retro theme resolve to the retro font stack — without touching the
   default theme.
