Engineering docs index

An indexed documentation area explaining how DekEn's solver engines and calculators work internally and how to use them — the technical companion to the articles CMS.

• You need to understand a solver's assumptions or limitations before citing its result
• You're integrating with the API and want conceptual docs alongside the generated OpenAPI reference
• You're a new contributor mapping the codebase to its documented architecture

Docs are organized by engine/subsystem (solver, transient, gas/two-phase, PHA) and cross-link to the relevant calculator or builder page rather than standing alone.
