/* wick.css — the page.

   THE SURFACE DIVISION, written here and obeyed everywhere. Every colour comes
   from css/tokens.css, which tools/palette.mjs SOLVED and proved; a chromatic
   literal typed into this file is refused by tools/validate.mjs, because a brand
   hue typed into CSS is the thing that drifts.

     .ground     the photograph. Nothing sits directly on it: every word on this
                 site sits on a surface of its own. A sentence standing on a
                 picture is the recurring failure in this family of sites.
     .sheet      the THIN pane (--surface, 54% glass). Display type and graphic
                 panels only — 3:1 — because 54% glass over the dark end of this
                 photograph cannot carry body prose.
     .card       the BODY card (--surface-2, 66%). Every paragraph, label and
                 number — 4.5:1.
     .slab       the DENSE slab (--surface-3, 82%). Figures and tables.
     .band       the one dark band. Type never sits on the band itself; it sits
                 on a .band .card, which is proved against it.

   The glass is thin on purpose. A big pane of 82% white over a blurred
   photograph IS a fill whatever the CSS says, and this family has shipped
   near-white-on-near-white nineteen times. tools/audit-live.mjs measures the
   painted pixels of every built page and refuses a frame flatter than the
   reference's flattest. */
