-MEAL ENHANCEMENTS - WORKING!
+EDIT MEAL FEATURE - IMPLEMENTED
 
-=== ✅ IMPLEMENTATION COMPLETE ===
+=== ✅ NEW FEATURE ===
 
-Meals now have:
+You can now EDIT existing meals!
-1. Instructions (multi-line)
-2. Prep time (minutes)
-3. Image (URL)
 
-=== IF MEALS/WEEK PLAN TABS DON'T LOAD ===
+Click "Edit" button → Modal opens → Make changes → Save
 
-Your database needs the new columns!
+=== HOW IT WORKS ===
 
-SOLUTION - Option 1 (Fresh start):
+1. Click "Edit" button on any meal
-rm mealprep.db
+2. Modal dialog opens with form
-./start.sh
+3. All fields pre-filled with current values:
-
-SOLUTION - Option 2 (Keep data):
-Just restart the server - migration runs automatically!
-./start.sh
-
-The migration will:
-- Check if new columns exist
-- Add them if missing (instructions, prep_time, image_url)
-- Keep all your existing data
-- No data loss
-
-=== HOW TO VERIFY ===
-
-After restart:
-1. Go to Meals tab
-2. Form should have:
    - Name
    - Description  
-   - Type dropdown
+   - Type (breakfast/lunch/snack)
-   - Prep time (NEW)
+   - Prep time
-   - Image URL (NEW)
+   - Image URL
-   - Instructions textarea (NEW)
+   - Instructions
+4. Change what you want
+5. Click "Save" → Modal closes, meal updates
+6. Click "Cancel" → Modal closes, no changes
 
-If you see the new fields, it's working!
+=== SECURITY ===
 
-=== FEATURES ===
+✅ User isolation enforced:
+   - GetMealByID(userID, mealID) verifies ownership
+   - Users CANNOT edit others' meals
+   - Users CANNOT access others' meal data
+   - UPDATE query filters by user_id
+   - All queries parameterized (SQL injection safe)
 
-Instructions:
+✅ Modal security:
-- Multi-line textarea
+   - Closes on click outside
-- Click to expand/collapse on meal card
+   - Close button works
-- Optional
+   - No data exposed
+   - XSS protected (template escaping)
 
-Prep Time:
+=== UI FEATURES ===
-- Number input (minutes)
-- Shows as "⏱️ XX min" badge
-- Optional
 
-Image:
+Modal Dialog:
-- URL input
+- Semi-transparent overlay
-- Shows as 120x120px thumbnail
+- Centered white box
-- Optional
+- All fields editable
+- Save button (blue)
+- Cancel button (gray)
+- Click outside to close
+- Clean, professional design
 
-=== ALL FIELDS OPTIONAL ===
+Buttons:
+- Edit (orange) - opens modal
+- Save (blue) - updates meal
+- Cancel (gray) - closes modal
 
-You can:
+=== WHAT CAN BE EDITED ===
-- Leave them blank
-- Fill only some
-- Fill all of them
 
-Old meals without these fields work fine!
+Everything:
+- ✅ Name
+- ✅ Description
+- ✅ Meal type (breakfast/lunch/snack)
+- ✅ Prep time
+- ✅ Image URL
+- ✅ Instructions
+
+=== AFTER SAVE ===
+
+- Modal closes automatically
+- Meal card updates instantly
+- No page reload (HTMX)
+- All changes visible immediately
+- Edit button still works
+
+=== CODE CHANGES ===
+
+handlers/meals.go:
+- GetEditMealHandler() - shows modal with form
+- UpdateMealHandler() - saves changes with security
+- Added Edit button to meal cards
+
+main.go:
+- /meals/:id/edit route (GET)
+- /meals/:id/update route (POST)
+
+static/styles.css:
+- Modal overlay styles
+- Modal content styles
+- Form styles
+- Button styles
+
+=== SECURITY CHECKS ===
+
+Edit Modal:
+1. Check session (middleware)
+2. Get userID from context
+3. Verify meal ownership
+4. Show form if authorized
+5. 404 if not found/unauthorized
+
+Update:
+1. Check session (middleware)
+2. Get userID from context
+3. Verify meal ownership BEFORE update
+4. Validate all inputs
+5. Validate meal type
+6. UPDATE with user_id filter
+7. Return 403 if unauthorized
+
+SQL Queries:
+- All parameterized
+- No string concatenation
+- User isolation enforced
+- No SQL injection possible
 
 === READY TO USE ===
