   Viska document stylesheet — institutional_dense register
   ----------------------------------------------------------------------------
   EVERY visual decision is a token in the :root block below. Nothing downstream
   carries a raw value. To restyle, edit tokens here — index.html carries content
   and semantic classes only and contains no inline style.

   Anchored to src/index.css @theme and brand/viska.brand.json. Values are quoted
   from those sources, never invented.

   LAYOUT LAW FOR THIS DOCUMENT — read before changing anything:
     1. CONTENT USES THE FULL MEASURE. There is no document-wide prose cap. Long
        text is set in COLUMNS across the page, never in one narrow ribbon with
        dead space beside it. --col-min is what controls readability, by setting
        how narrow a column may get before the grid drops one.
     2. NO <h1>. The masthead is a compact band, not a title page.
     3. Vertical space is expensive. --section-y and --pad-box are deliberately
        tight; raise them only with a reason.

   Quick knobs, most-wanted first:
     --w-page      page measure
     --col-min     column floor — LOWER packs more columns in, raising density
     --density     scales table + box padding + section rhythm together
     --fs-base     root size; the whole scale is relative
     --radius      0 = institutional square. 4px softens everything at once.
     --sign-pos / --sign-neg    the P&L sign colours, everywhere
     --accent      gold; the eyebrow / rule / kpi accent
