This is an impressive design brief for a Research Board application! Let me generate design inspiration to ensure the visual implementation captures this scientific, minimalist aesthetic, and then create a structured plan to build this.

Now let me update the globals.css with the scientific instrument theme specified in the brief, and start building the board shell and components.

Now let me update the layout metadata and create the core type definitions and board components:

Now let me create the board shell components - the header and the main canvas:

Now let me move to the next task and create the block system:

Now let me create all the different block type components:

Now let me create the remaining block types:

Now let me create the remaining blocks (dataset, file, voice-note), the block index file, and the main board canvas:

Now let me create the main board canvas and connections overlay:

Now let me create the main Board component that ties everything together, and the page:

Now let me check the package.json to see if we need to add any dependencies:

I need to add zustand for state management and framer-motion for animations:

I've built the complete Research Board application following your detailed design brief. Here's what's been created:

Board Shell & Layout:

• Clean, minimalist header with inline-editable board name, milestone, and status
• Toggle for connection view
• Near-white background (#FAFAFA) with precise typography

Block System (15 block types):

• Research Blocks: Hypothesis (with status badges), Result (confidence levels), Decision (impact indicators), Question (status tracking), Method (expandable steps)
• Content Blocks: Text, Heading (H1/H2/H3), Note (with tags), Checklist (animated checkboxes), Comparison (pros/cons table)
• Attachment Blocks: Code (syntax highlighting, language picker), Dataset (table preview), Literature (citation format with DOI), File (drag-and-drop upload), Voice Note (recording)

Interactions:

• Notion-like / command menu for block type selection
• Keyboard shortcuts (Enter, Backspace, Cmd+D, arrow navigation)
• Block actions on hover (duplicate, delete, connect, branch, restructure)
• Framer Motion animations throughout

Connections & Branches:

• Visual connection overlay with curved lines and labels
• Support for relationship types (supports, contradicts, depends-on, leads-to)
• Branch system for parallel trains of thought

Neural Core:

• Fixed bottom input with purple accent (the AI signature color)
• Keyboard shortcut (Cmd+K) activation
• Context-aware prompts when blocks are selected
• Mock responses demonstrating the interaction pattern
