   Typographic alignment with the printer's-device wordmark
   (thinkshop_alt_dark_horz.svg, 56px tall):
     - Wordmark visible baseline sits ~39px below the SVG top
     - IMG element's CSS-baseline is at the SVG bottom (56px)
     - Therefore: align-items: baseline aligns nav text 17px BELOW the
       visible wordmark baseline by default
     - We compensate via translateY(-17px) on the nav, lifting its baseline
       to match the wordmark's visual baseline
   Font size bumped from --type-font-size-xs (0.7rem) to --type-font-size-md (1.05rem)
   to match the wordmark's x-height. The wordmark x-height is ~13-14px;
   --type-font-size-md in Inter gives ~9.5px x-height — visually close, deliberately
   slightly smaller so the wordmark stays primary.
