Reference
Updates to the atlas, newest first. Tagged feature, content, fix, perf, or chore.
/changelog shows what's new, tagged feature / content / fix / perf / chore, with newest first. The 'What's new' sidebar link surfaces an amber dot until you visit. /compare lets you put two archetypes side-by-side across the seven-finding vocabulary, highlighting shared vs discriminating features for the bedside differential.
/print-all compiles every module heading, the manoeuvre library, instrument scoring rules, archetype profiles, the glossary, and the references into a single document optimised for paper. Uses A4 page geometry, 16 mm margins, widows/orphans 3, and break-inside-avoid on figures.
/glossary lists 48 terms across anatomy, examination, workup, conditions, manoeuvres, and concepts. Each carries aliases (so 'VOR' resolves to vestibulo-ocular reflex, 'Bow Hunter' to RVAS), see-also cross-links, and deep links to the relevant module. Bookmark stars persist per-user via localStorage. Press / to focus search.
/practice generates synthetic clinical cases from 9 disease archetypes, asking the user to tick which of the 7-finding vocabulary apply and pick the most likely diagnosis. Two-axis grading — feature identification and diagnostic choice — with running stats persisted locally. Mulberry32 PRNG provides deterministic seed-based replayability.
/quiz now has 30 single-best-answer questions across the seven topic areas at three reader levels. Browse mode for filter-then-explore; Spaced review with either Leitner (5 boxes, 10min/1d/3d/7d/21d) or 3-in-a-row streak scheduling; Timed mode (10 questions in 5 minutes with personal-best tracking and per-question summary review).
Five clinical tools under /tools: validated DHI (Jacobson-Newman 1990, 25 items, subscale-bar live scoring) and NDI (Vernon-Mior 1991, 10 sections, raw + percent + Vernon-Mior bands) calculators, a clinic-mode wrapper around the DDx engine, an interactive stepper-driven BPPV manoeuvre library (Dix-Hallpike, supine roll, Epley, Semont, Lempert), and A4-printable patient handouts mapped to the four mechanism routes.
Hand-authored single-best-answer cases covering office-worker proprioceptive, whiplash, vestibular migraine with cervical features, BPPV in a truck driver, RVAS while reversing, sympathetic-dominant yoga teacher, tinnitus + schwannoma, and failed-manual-therapy PPPD. Per-case completion tracked in localStorage; filterable by level. Static prerendering via generateStaticParams; prev/next navigation.
Module 02 (Functional Anatomy), 03 (Pathophysiology), 04 (Clinical Examination), 05 (Vestibular Workup), 06 (Imaging & Vascular Studies), 07 (Differential Diagnosis), and 08 (Management) are complete across the Foundation / Trainee / Clinician layered content system. Every clinical claim cites peer-reviewed primary sources via the Reference registry.
The /references page renders from a single typed registry. Every clinical claim across the atlas uses <Cite id=...> to point into this registry, so adding a paper, fixing an author, or updating a DOI is a single-source-of-truth edit. Citations link out to PubMed or DOI where available.
Initial scaffold on Next.js 16 + React 19 with App Router, static export, ESLint flat config (native eslint-config-next exports — no FlatCompat), and TypeScript strict + noUncheckedIndexedAccess as baseline. Theming via CSS custom properties with warm-paper light and warm-ink dark palettes, prefers-color-scheme respected, pre-hydration inline script to prevent flash-of-wrong-theme, reduced-motion respected throughout.
