   Chiemi Shimada — portfolio
   Plain, gallery-grid design matching the original Google Sites layout:
   a solid dark header bar, a plain underlined text nav, and a simple grid
   of image thumbnails with bold titles and grey medium tags underneath.
   No colour accents, no decorative motion — the work carries the page.
