/* ── Once For All — Performance Management UI reconstruction ────────────────
   A component set that rebuilds the Performance Management screens in
   HTML/CSS, so the case-study visuals stay sharp at any resolution and can be
   cropped to the exact fragment a section needs.

   THESE ARE RECONSTRUCTIONS. Every screen assembled from these components is
   redrawn from the two hand-off prototypes — Supply Chain Manager and Project
   Manager. Colours, type, spacing, labels, statuses and figures are taken from
   those files (the Apex design-system tokens they ship with: brand #3B2D6D,
   ink #280071, primary action #DA1884, status containers #FFF7E2 / #EFFFF1 /
   #FFEDED / #F4F7FB). They are cleaned up but NOT redesigned.

   Everything is scoped under `.ofa-app` / `.ofa-scope` so it cannot leak into
   the portfolio shell. Class prefix `ofa-` = Once For All.
