From 8c54ede6ebdd55efbfa39c25f52fdc6988cb8cfc Mon Sep 17 00:00:00 2001 From: Edwin van den Houdt Date: Thu, 23 Jul 2026 15:43:53 +0200 Subject: [PATCH] =?UTF-8?q?feat(showcase):=20PII=20section=20=E2=80=94=20m?= =?UTF-8?q?ask=20+=20elfproef=20parse=20(WP-42,=20mask/parse=20half)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a "PII — maskeren & parsen" section to /concepts demonstrating the WP-40 pieces with FP + atomic design, framed for AVG art. 9 / data-minimisation: a live atom (masked BSN that reveals on click; real reveal is step-up + audited in behandel-scherm) and a live parseBsn elfproef parse. Both show the real linked source via the WP-39 snippet mechanism (new showcase regions in bsn.ts + pii.ts, registered in gen-snippets.mjs).
