/* Zkwail website — shared design tokens & chrome.
   Single source of truth for the header/nav, footer, buttons, base
   resets, and the glass/motion module (frosted cards, shine sweep,
   buttery easing). Page-specific layout stays inline in each page's
   own <style> block; this file is only what's identical everywhere.
   Loaded via <link> AFTER each page's inline <style> so .glass/.glass-dark
   still win the cascade over page-local card backgrounds (.fcard, .dcard,
   .ccard, etc.) that are defined earlier, inline. Don't move the <link>
   above the inline <style> without also re-checking that override order. */
