Validation cross-check pages

Published, page-by-page cross-checks of DekEn's solver output against independent references — EPANET benchmark networks, FluidFlow validation cases, and Crane TP-410 worked examples — each showing the comparison data alongside the result.

• You need evidence a specific engine (steady GGA, two-phase, gas) matches an accepted reference before you stake a design on it
• A reviewer or client is asking 'how do you know this solver is right?'
• You want the actual comparison numbers, not just a claim of accuracy

Each validation page loads a fixed comparison-data set (e.g. EPANET Net2, FluidFlow Case 7) and re-solves it live with DekEn's own engine, rendering DekEn's numbers next to the reference's so any drift is visible immediately rather than hidden in a static screenshot.
