/* =============================================================================
   zacharybhenley.com v2 — shared design system
   Read this block before building a new page. Nothing here is home-specific
   except the block explicitly marked "HOME PAGE SCENES" near the bottom —
   everything above that line is the shared foundation other pages reuse.

   LAYOUT
     .wrap                 max-width content container (--maxw / --pad)
     .section              full-bleed section, vertical rhythm padding, bg var(--bg)
     .section--alt         bg var(--bg-alt) (the "gray" Apple alternation)
     .section--pro         forced-dark "Pro" section (always dark, both themes)
     .section__head        title + sub wrapper used at the top of most sections

   TYPOGRAPHY
     .eyebrow               small colored label, set --accent to recolor
     .display-xl / -l / -m  the three display sizes from the spec
     .body-l / .body        paragraph sizes
     .caption                14px ink-3, tabular figures

   COMPONENTS
     .btn, .btn--primary, .btn--secondary, .btn--sm     buttons (pill primary)
     .link-more                                          text link with › chevron
     .chip, .chip__dot                                   status chip, pulsing dot
     .tile, .tile--wide, .tile--pro                       28px rounded card
     .figure, .figure__value/__label/__source/__viz      big-number figure
     .grid--asymmetric                                    1 wide + N narrow tiles

   ACCENT SYSTEM
     Set `style="--accent:var(--acc-solar)"` (or --acc-dasalla / --acc-founder)
     on a wrapping element; .eyebrow, .tile__glow, chart marks etc. read
     var(--accent, var(--blue)) so one declaration recolors a whole card.

   MOTION HOOKS (see /assets/js/site.js)
     [data-reveal]                 fades/rises in once, on scroll into view
     [data-reveal="lines"]         SplitText line-mask reveal (falls back to fade)
     [data-split]                  text container SplitText will split into lines
     [data-draw]                   SVG shape that draws on scroll-into-view
       [data-draw="stroke"]        stroke-dashoffset 1 → 0 (path needs pathLength="1")
       [data-draw="scalex"]        scaleX 0 → 1 (bars/underlines), transform-origin left
       [data-draw="scaley"]        scaleY 0 → 1 (vertical bars), transform-origin bottom
       [data-draw-delay="120"]     optional stagger delay in ms
     [data-copy-email]             click-to-copy button, data-email="…" data-copied-label="…"
     Everything above is fully visible with zero JS; JS only hides-then-reveals
     when GSAP actually loaded (see site.js), so a CDN failure never hides content.

   VIEW TRANSITIONS
     Cross-document view-transitions are enabled site-wide below. Shared elements
     carry inline `style="view-transition-name: wt-<slug>"` (card/case title) and
     `wv-<slug>` (card/case visual) directly in the page markup — set both ends
     to the same name so future case-study pages morph from the home cards.
