/* Hallmark · genre: atmospheric · macrostructure: Bento Grid · theme: studied-DNA
 * DNA-source: url — https://santifer.io/ · studied: yes · RE-VERIFIED via live computed styles
 * (Claude in Chrome, not just fetch/meta this pass). Corrected from the previous pass:
 * paper is dark zinc #18181B (not pure black), accent is a cyan→purple GRADIENT #20D6EE→#C794FA
 * (not solid coral), type is DM Sans (body) + Space Grotesk (display) — no monospace anywhere
 * on the source. Borders are solid #313135, cards are 12px radius, buttons/badges fully pill.
 * nav: source has no persistent nav (top-right lang+theme toggle only) — kept ours as a
 * deliberate UX exception since this page is longer/multi-section; restyled to match tokens.
 * footer: Ft2 (centered single line) · rhythm: informed by live screenshot this pass
