A blood film, worked the way you would on the bench

What it is

One real case a month, presented as a bench workflow rather than a quiz. The learner reads the history and the blood count, decides which results matter, examines the film with a magnifier, rings the cells they can name, builds a differential and commits to it once.

Only then do the confirmatory results open up. The case marks what they called, shows the model answer with every rule-out linked back to the result that settles it, and issues a CPD record and certificate they can keep.

What I built

• One self-contained page — vanilla JS, no framework, no build step — that drops straight into the client's own site and inherits its theme, header and help panel.
• Content lives in a structured file, not the markup, so next month's case is authored rather than coded, and the build refuses a case with a broken link or a missing answer.
• Checked as the real page in both themes at desktop and phone sizes: contrast measured across every text node, keyboard and focus behaviour, and the certificate export verified.
• Progress and reflections save locally, so a case can be picked up where it was left.
