/* DNA Synthesis Screening Tracker
 *
 * Design intent: a reference instrument, not an article with a table in it.
 * The table is the product, so it gets the full width and the strongest
 * contrast; prose is support and stays out of its way.
 *
 * The hardest constraint is that most cells currently read "Unverified". If
 * every state is styled with equal weight, 11 grey rows dominate the page and
 * the thing looks broken rather than in-progress. So verified states carry the
 * colour and weight, and unverified recedes almost to the background — present,
 * honest, but not shouting.
