/* Station70 architecture stylesheet. Loaded (via ) by the three reference-architecture listing pages (architectures.html for Gatekeeper, bunker-architectures.html, castle-architectures.html) and every architecture-*.html deep-dive page. Extracted from what used to be per-element inline `style`/`style-hover`/ `style-active` attributes — see CLAUDE.md's DC runtime section for why inline styles are otherwise this codebase's default, and blog.css/ careers.css (this file's siblings) for the same treatment applied elsewhere. The 3 listing pages share one hero/grid/card skeleton and the 16 deep-dive pages share another (hero, diagram, dataflow, components, security considerations, CTA) — see "Operational notes" in CLAUDE.md — so classes here are reused across all 19 files rather than duplicated. Colors are CSS custom properties from color-tokens.css (this file's shared token source, loaded alongside it) or colors_and_type.css's sitewide tokens, never literals — same convention as blog.css/careers.css. */ /* ---------- Base reset + keyframes ---------- Previously an identical inline
