/* ============================================================
   Showcase — the Hairline figure above the project list, and the
   category colours used across the work section.

   The four category hues were run through the dataviz palette
   validator against --surface in both modes. Light passes outright;
   dark warns on amber/green under protanopia (ΔE 6.2), which is
   legal with secondary encoding — every place a hue appears it also
   has its name beside it (key, filter tab, card kicker, panel), and
   the card file punches the category in one of four tab positions.
