   To change it, replace the base64 below (or swap these rules

/* ============================================================
   NEW — HERO FIGURE + LIGHTBOX
   The workflow comparison graphic carries the core argument, so
   it sits in the hero. Its smallest labels are ~14px in a
   1672px raster: at phone width they land around 3px and are
   not meant to be read in place. Tapping opens a full-screen,
   pannable view at 1200px where every label is legible. The shipped
   raster is the no-title export (1672×719); the page h1 carries the title. The
   img alt text carries the full description, so a screen reader
   needs neither the zoom nor the pan.

   ASSET PATHS ARE RELATIVE. That is correct when the page is
   served as /standards.html with assets/ alongside it. If you
   serve it as /standards/index.html instead, change these to
   root-absolute (/assets/...) or the figure 404s — same trap
   the brand mark fell into.
