   Self-hosted. No external requests: fonts are local, graphics are inline.

   Palette reasoning: the page is near-monochrome graphite, because dark-field
   microscopy is the authentic visual register of her work. The single accent is
   shikonin — the red-violet naphthoquinone at the centre of her thesis — so the
   one saturated colour on the page is literally the subject of the research.
