Configuração do Supabase:
Crie estas tabelas no SQL Editor do seu Supabase:

create table profiles (
  id uuid primary key references auth.users(id) on delete cascade,
  full_name text,
  role text check (role in ('nutricionista','aluno')),
  nutricionista_id uuid references profiles(id),
  age int, height numeric, gender text, goal text,
  created_at timestamp default now()
);
create table plans (
  id uuid primary key default gen_random_uuid(),
  student_id uuid references profiles(id),
  nutricionista_id uuid references profiles(id),
  title text, content text, plan_type text,
  created_at timestamp default now()
);
create table weight_logs (
  id uuid primary key default gen_random_uuid(),
  student_id uuid references profiles(id),
  weight numeric, notes text,
  logged_at timestamp default now()
);
alter table profiles enable row level security;
alter table plans enable row level security;
alter table weight_logs enable row level security;
create policy "users read own" on profiles for select using (true);
create policy "users update own" on profiles for update using (auth.uid() = id);
create policy "users insert own" on profiles for insert with check (auth.uid() = id);
create policy "plans read" on plans for select using (true);
create policy "plans insert" on plans for insert with check (true);
create policy "weight read" on weight_logs for select using (true);
create policy "weight insert" on weight_logs for insert with check (true);

-- Tabela de fotos de evolução (necessária para "Gerar Meu Plano"):
create table fotos_evolucao (
  id uuid primary key default gen_random_uuid(),
  student_id uuid references profiles(id) on delete cascade,
  photo_url text not null,
  label text,
  peso numeric,
  registered_at timestamp default now()
);
alter table fotos_evolucao enable row level security;
create policy "fotos read" on fotos_evolucao for select using (true);
create policy "fotos insert" on fotos_evolucao for insert with check (true);

create table plan_attachments (
  id uuid primary key default gen_random_uuid(),
  plan_id uuid references plans(id) on delete cascade,
  file_name text,
  file_type text,
  file_url text,
  created_at timestamp default now()
);
alter table plan_attachments enable row level security;
create policy "attachments read" on plan_attachments for select using (true);
create policy "attachments insert" on plan_attachments for insert with check (true);

-- Bucket de armazenamento de fotos (criar no Supabase Storage):
-- Nome: fotos-alunos | Tipo: privado

-- Migração para bancos existentes (execute se as tabelas já existirem):
alter table profiles add column if not exists email text;
alter table plans add column if not exists plan_attachments_saved boolean default false;
