/* Personal homepage for Dr Harjinder Singh Lallie, OBE
   Look and feel: bold grotesque headings, generous white space, a dark stats band,
   small spaced-out labels, square-cornered buttons.
   Palette: deep teal ink with a saffron accent.
   Edit the colours in :root and the whole site follows. */
