/**

 * SOURCE FIDELITY RULES APPLIED HERE
 *  - Every title, instruction, prompt, quote and table value below is copied
 *    verbatim from the source document. Nothing medical is paraphrased,
 *    summarised or invented.
 *  - Where the source repeats an identical paper template (20 case planning
 *    sheets, 10 jet maps, 10 case logs, 50 teaching entries), the template is
 *    modelled ONCE as a repeatable activity and the source's copy count is
 *    recorded in `config.suggestedCopies`. The app lets a learner create as
 *    many entries as they need, so duplicating the row 20 times would add no
 *    information.
 *  - Blank cells in the source are answer spaces for the learner and are
 *    preserved as empty fields, not filled in.
