/* ============================================================
   allisterk.com — hub.css · v5 (self-contained)
   ------------------------------------------------------------
   The hub's complete stylesheet. No shared/common assets: the
   foundation (tokens, type, palette) that used to come from
   tokens.css is inlined below with the hub's own values
   (golden-pollen pigment on warm paper) already resolved.

   The design language, stated once and obeyed everywhere:

   1. TWO levels, and the level is legible from the unit.
      SITES are the page: a full-width row, one per line —
        [ 3.25rem logo tile ] [ name + one-liner ] [ mono meta, right ]
      TOOLS are a footnote to it: a 3-across card, name at ~60% of
      the row-name's size, no logo tile on the shared left axis.
      Hairline separators either way. No boxes, no mats.
   2. Logos sit directly on the paper — object-fit: contain in a
      fixed square, never cropped, never framed.
   3. Ink on paper. A destination's pigment appears ONLY on hover
      (a quiet wash + the name). Color is a reward, not decoration.
      Every listed thing answers the cursor, including the ones with
      no URL to go to.
   4. Two faces, few sizes: Crimson Pro for names and prose,
      JetBrains Mono for labels and addresses.
   5. Nothing is decorated. The page is whitespace and 1px lines —
      the striped bar over Sites is gone.
   6. Rhythm: 4.5rem between sections, 2.75rem down to a subsection,
      1.5rem inside rows.

     Every destination's pigment, because the hub is the one page
     that shows all of them: `hub_pigment_style()` in _lib/render.php
     writes `--pigment: var(--pg-<name>)` onto each site row so the
     row hovers in the colour of the place it goes.

     These lived in the old shared tokens.css. When v4 went
     self-contained that file was deleted and these were not carried
     over, so every site row was setting --pigment to an undefined
     variable — which made `color-mix()` invalid and silently killed
     the hover wash, the name colour and the arrow. The tools rows
     had no inline style, inherited the pollen values above, and kept
     working: hence "sites no longer hover like g-code generators".
     Contrast figures are against warm paper / against ink. */
