   TheShadowLab — shared site stylesheet
   Loaded on every page. Contains only chrome that is identical site-wide:
   reset, color theme (dark/light), theme toggle button, top-bar/breadcrumb,
   footer, and the fadeUp entrance animation. Page-specific layout (hero
   sections, card grids, etc.) stays in each page's own <style> block.
