Build a multi-survey management platform for EWN (Energy Worldnet) called the EWN Survey Platform. TECH STACK React + TypeScript, Tailwind CSS, Supabase (auth + database + RLS), shadcn/ui components, @dnd-kit/sortable for drag-to-reorder. BRAND & DESIGN Font: Inter (all weights). Colors: - OQ Blue #284249 (primary, buttons, section headers, headings) - EWN Yellow #FFD400 (accents, badges, progress fill, logo on dark) - Deep Navy #042B35 (page-level headers and nav bars) - Teal Accent #1D7183 (focus rings, links, hover states) - Page background #DDE8E5 - Cards: white, 1px #e5e7eb border, 12px border-radius Logo: an SVG "E" mark I will supply (ewn-e.svg). Use it yellow on dark backgrounds, OQ Blue on light backgrounds. DATABASE (create via Supabase) Table: surveys id uuid PK default gen_random_uuid() name text not null description text location_tag text status text default 'draft' -- 'draft' | 'active' | 'closed' slug text unique not null created_by uuid references auth.users created_at timestamptz default now() published_at timestamptz closed_at timestamptz Table: sections id uuid PK default gen_random_uuid() survey_id uuid references surveys on delete cascade title text not null order_index integer not null default 0 Table: questions id uuid PK default gen_random_uuid() section_id uuid references sections on delete cascade text text not null type text not null default 'likert' -- 'likert' | 'open_ended' required boolean default true affects_score boolean default true order_index integer not null default 0 Table: responses id uuid PK default gen_random_uuid() survey_id uuid references surveys on delete cascade submitted_at timestamptz default now() answers jsonb not null default '{}' email_copy_requested boolean default false RLS: - responses: INSERT allowed without auth (public can submit). SELECT/UPDATE/DELETE require authenticated admin. - surveys, sections, questions: all operations require authenticated user. USER ROLES Admin: authenticated via Supabase Auth (email+password to start; Microsoft SSO as future enhancement). Full access to all /admin routes. Respondent: no login. Access /survey/:slug only. PAGE 1 — /admin (Survey Library) Full-width dark header (#042B35): EWN logo (yellow SVG), title "Survey Library", yellow "ADMIN" badge. Right side: "New Survey" button (white outline style). Below header: filter tabs (All / Draft / Active / Closed) + table of surveys. Table columns: Survey Name, Location, Status badge, Responses count, Created date, Actions. Status badges: Draft=grey, Active=#35A552 green, Closed=slate. Row actions: Edit (opens builder), Results (opens dashboard), Clone (duplicates as draft), Archive. "New Survey" opens a modal: name field (required), description textarea, location tag input, optional clone-from select. Submit creates a draft and redirects to the builder. Empty state: friendly card with EWN logo and "No surveys yet. Create your first one." PAGE 2 — /admin/surveys/:id/edit (Survey Builder) Top bar: inline-editable survey name, status chip, Preview button, Publish button. Two-panel layout: left panel (280px) lists sections with drag handles and a + Add Section button. Right panel shows questions for the selected section with + Add Question button. Each question row: drag handle, question text (truncated), type chip (Likert / Open-Ended), edit and delete icons. Question edit form (slide-out panel or inline): text textarea, type radio (Likert / Open-Ended), required toggle, affects_score toggle. Publish action: set status to active, set published_at, show toast with the shareable URL (/survey/:slug) and a copy button. Preview button: renders a full-screen modal showing the exact public form. PAGE 3 — /admin/surveys/:id/results (Results Dashboard) Header: EWN logo + "Results: [Survey Name]" + Back to Library link + Export CSV button. Stats row (4 cards): Total Responses | Overall Avg Score (x.xx / 5) | Score % | Sections. Tab bar: "Section Scores" | "Open-Ended Responses". Section Scores tab: one card per section. Each shows a colored score badge (score>=4.5: #35A552, >=3.5: #1D7183, >=2.5: #B8860B, else: #CD3D3D), section title, score progress bar (0-5 scale), question count + response count. Clicking a section expands it to show per-question rows: question text on left, avg score + 5-segment mini distribution bar on right (SA=green, A=teal, N=light grey, D=amber/yellow, SD=red). Open-Ended tab: for each open-ended question, show the question text as a heading and all non-empty text responses in teal-tinted cards. Show response count. Export CSV: download all responses as CSV (one row per response, columns: submitted_at + one column per question id + email_copy_requested). If no responses yet: friendly empty state per tab. PAGE 4 — /survey/:slug (Public Survey Form) Load survey + sections + questions from Supabase using the slug. No auth required. If survey.status === 'closed': show centered screen with EWN logo, "This survey is no longer accepting responses.", and a thank-you message. If survey not found: show 404 screen. If survey.status === 'draft': treat as not found. If survey.status === 'active': render the form. Form layout: - Dark header (#042B35): EWN logo (yellow), survey name (white, 1.6rem bold), description (muted #9FBCC4). - Sticky sub-bar below header (#042B35 slightly lighter or same): progress bar track with yellow fill, "X of Y answered" label.
