Split the Bedside clinical reference section out of calculators.js (~1220 lines) into 20 focused ES modules under public/js/bedside/. Each module owns one clinical topic (cardiac, seizure, sepsis, burns, etc.) and exports an init() wired up by bedside/index.js. Shared helpers live in shared.js and also set window._EM for back-compat with the 4 remaining call sites in calculators.js. Load order: classic defer calculators.js first, then module script bedside/index.js. Handlers bind at DOM-ready; runtime _EM lookups resolve after both are evaluated. Makes bedside content editable per-section, shrinks calculators.js from 4111 to 2891 lines, and keeps the existing Playwright smoke suite (e2e/tests/bedside-smoke.spec.js) as the behavioral contract.
