M8: interactive space-time (Hovmoller) panel -- watch the wave ridge tilt as the pulse grows; celerity read off the slope

M8: add measured computational characteristics of lr vs kw (cost scaling, Newton iteration counts, walk length)

Reframe routing as ONE topic on two axes (method x space); add unifying experiment: emergent GIUH, what space buys, no unique UH for nonlinear KW

M8: step-by-step trace panel (every intermediate of lr walk & kw Newton iterations), interactive

Module 8b: complete CREST routing anatomy (lr vs kw) -- travel-time delivery implemented, side-by-side interactive comparison, three source-level findings

Module 8a (channel network routing): cell-to-cell KW on Y network, topological sweep, wave profile + confluence, EF5 mechanics anchored

Module 7 (routing deep-dive): FIR/IIR/PDE schools, 5 editable versions, nonlinearity probe (5 vs 50mm pulses), EF5 KW Newton scheme, live NSE

Module 6 (response reservoirs): 4 editable versions, live NSE vs obs, log-scale baseflow view, pulse-response IUH panel

M5: interactive CREST variable-infiltration-curve geometry (live P/wetness/B/FC sliders, area shading, full wet-branch pipeline readout)

M5: case switcher (humid Hesperange / synthetic arid hourly) + V5 Horton-cap + V3 replaced by literal CRESTModel.cpp transcription (parity 3.6e-15)

Module 5 (runoff generation): 4 editable versions (bucket/HBV-beta/CREST-VIC/SCS-CN) with per-version sliders, live soil state + runoff plots

Restructure: multi-page interactive course (nav home + per-module pages with editable/runnable code, version tabs w/ CREST tag, live plots)

Module 2 (PET): GivenPET/Hamon/Hargreaves comparison + KE scaling; advance pointer to soil water balance

Module 1 (Forcing): spatial aggregation methods + cal/val split; advance pointer to PET

Add Hesperange site section + catchment/outlet schematic

Fix glyph rendering (HTML entities), add bilingual glossary + SVG diagrams

Module 0-1: static Pyodide app (water balance, forcing, reservoir playground)
