/* ── Entry pages (single.php) ─────────────────
   Every entry – projects, news, publications, topics, student works, profiles – in
   three equal columns: title, year and summary | text | Information, Team and links
   (profiles: portrait and name | bio | projects, publications …). Narrower screens:
   two equal columns (title and summary above the text | right column), then one.
   Every rule starts with body.dbt-3col (the class of entry pages, functions.php),
   which also keeps them above the general rules for texts on pages (.entry-content).

   Three sizes: the title; the summary; and one small size for all other text – the
   text, the right column, captions – the size of the footer's lists, so the images
   and the white space carry the page. Otherwise the only differences are deliberate:
   bold (title, summary, headings, bold words, labels in the right column), grey for
   what is secondary (year, captions, roles), links (thin underline). Between
   paragraphs an empty line; a thin line where a new part starts. */
