   MedCases Pro — BUILD 235 (rev3 — GRID FINAL)
   feat(calculator): hierarchical responsive layout + full-width accordion

   ESCOPO EXCLUSIVO: UX / Layout / Hierarquia / Grid / Accordion
   NÃO altera: cálculos, fórmulas, banco de dados, ClCr,
               eletrólitos, infusões, adapters, lógica clínica.

   ║  ─────────────────────────────────────────────────────────  ║
   ║  TODOS FECHADOS  → container = CSS Grid (2 ou 4 colunas)    ║
   ║  QUALQUER ABERTO → container = flex-column (1 coluna 100%)  ║
   ║                    card aberto expande full-width            ║

   GRID SPEC:
   ┌─────────────────┬──────────┬──────────────────────┐
   │ Nível           │ Mobile   │ Tablet/Desktop ≥768px │
   ├─────────────────┼──────────┼──────────────────────┤
   │ N1 (3 cards)    │ 1 col    │ 1 col (cada na linha) │
   │ N2 (6 cards)    │ 2 col    │ 4 col                 │
   │ N3 (2 cards)    │ 2 col    │ 2 col                 │
   └─────────────────┴──────────┴──────────────────────┘

   TÉCNICA (grid→flex switch):
   JS adiciona .hub-accordion--expanded ao <nav#hub-accordion>
   quando qualquer card abre (_updateAccordionState(true)).
   CSS usa esse seletor para trocar display:grid → display:flex.
   Quando fecha, JS remove a classe e grid retorna automaticamente.

   ARQUITETURA:
   §1  Hub Accordion container
   §2  Nível 1 — full-width, 1 col sempre
   §3  Nível 2 — GRID: mobile 2col / tablet 4col
   §4  Nível 3 — GRID: sempre 2col
   §5  ESTADO EXPANDIDO — flex-column para N2 e N3
   §6  Microinterações e triggers
   §7  Tipografia hierárquica
   §8  Componentes internos (botões, inputs, footers)
   §9  Modo Claro
   §10 Overrides finais / anti-conflito

   CARREGAMENTO:
   1. medcases-ux-v2.css
   2. build233.css
   3. build234-design-system.css
   4. build235-layout.css  ← este arquivo (maior prioridade de cascade)

   ─────────────────────────────────────────────────────────────
   GATILHO: .hub-accordion--expanded adicionado ao <nav> pelo JS
   (_updateAccordionState(true) em hub-accordion.js)

   EFEITO:
   - Container abandona o grid completamente
   - Torna-se flex-column (coluna única)
   - Card aberto (.is-open) expande naturalmente a 100%
   - Cards fechados também ficam 100% (empilhados abaixo)
   - Quando JS remove .hub-accordion--expanded → grid retorna

   PRIORIDADE: !important + posição de cascade (carregado por último)
   garante sobrescrever qualquer regra de grid anterior,
   incluindo os media queries do §3.
