   LLAMMAG — neobrutalist stylesheet
   --------------------------------------------------------------------------
   Structure:
     1. Design tokens        — change the whole site from here
     2. Reset & base
     3. Typography
     4. Core components      — .card, .btn, .badge, .panel
     5. Layout               — header, footer, grids
     6. Page-specific        — hero, people, publications, codes
     7. Signature motif      — the spin lattice divider
     8. Responsive & a11y
   --------------------------------------------------------------------------
   The whole aesthetic is three rules applied consistently:
     border: var(--rule) solid var(--ink);
     box-shadow: var(--shadow-x) var(--shadow-y) 0 var(--ink);
     border-radius: 0;
