/* ---------------------------------------------------------------------------
   1. Fluid root sizing  —  fixes "size is not same on PC vs laptop"
   ---------------------------------------------------------------------------
   Every template sizes its text in rem (0.62rem .. 1.5rem). rem resolves
   against the ROOT font size, not body, so scaling :root is what makes the
   whole UI track the viewport.

       360px phone  -> 14.0px      1920px desktop -> 16.1px
      1366px laptop -> 15.4px      2560px+        -> 17.0px

   The curve is deliberately shallow: paddings and the 60px navbar are still
   fixed px, so text must not outgrow them.
   ------------------------------------------------------------------------- */
:root { font-size: clamp(14px, 0.1364vw + 13.51px, 17px); }

/* body was hard-coded to 14px in all 10 dashboard templates. 0.875rem is the
   same 14px at the default root, but now scales with the clamp above. */
body { font-size: 0.875rem; }

/* Logos etc. never force a horizontal scrollbar. Templates that pin an
   explicit height (.navbar-brand img, .portal-header img) are more specific
   and keep winning. */

   4. Pinned label column
   ---------------------------------------------------------------------------
   Below 1200px the wide tables scroll sideways, and without a pinned first
   column you lose track of which row you are reading.

   responsive.js tags each top-level table:
     .rt-pinned a cell is explicitly marked .rt-pin in the template — used
               where the first label is not the useful one (stock_report
               leads with a 4-digit plant code; Product is what identifies
               the row)
     .rt-num   first cell is the decorative {{ forloop.counter }} — dropped
               here, and the label (2nd cell) takes the pinned slot
     .rt-plain first cell IS the label — pinned directly

   The "#" header is always <th rowspan="2"> on the FIRST header row, so the
   hdr-cols row below must not be touched — hence tr:first-child.

   z-index budget. Several templates already stick their own header rows at
   z-index 5/6, which is exactly why an earlier pinned header rendered
   *underneath* the scrolling ones:
        12  pinned header cell   (must clear the page's own sticky headers)
         5  pinned cell in a sticky Grand Total row
         4  other cells of a sticky Grand Total row
         3  pinned body cell
