Redesign Deal Details Overlay

## Overview

The objective of this task is to completely redesign the "Deal Details" overlay in the dashboard (`templates/dashboard.html`) to match the provided concept image (`image.png`). The new design replaces the tabbed interface with a high-density, 4-column grid layout that consolidates all critical decision-making data into a single view.

## 1. Visual & Layout Requirements (Frontend)

Refer to `image.png` for the visual reference, and style guidelines.

### General Layout

- **Remove Header:** The standard modal header (containing Title and ASIN) must be **removed**. This information is now integrated into the table below.
- "Advice from Ava" Section:
  - Positioned at the very top of the overlay, *above* the data table.
  - Styled to match the data cells (light background, border).
  - **Content:** Displays the AI-generated advice text.
  - **Style:** "Advice from Ava" label in bold, followed by the text.
- Action Bar (Top Right):
  - **Gated Status:** Display a checkmark (✔) or "apply" button (The same thing we do on the dashboard page itself).
  - **Buy Now Button:** A button styled similarly to the dashboard "Reset" button.

### Data Grid Structure

The main content is a 4-column grid. Use a CSS Grid or Table layout to achieve alignment.

#### Group 1: Book Details

- **Header:** "Book Details"
- Rows:
  - **ASIN**: Display ASIN.
  - **Title**: Truncate with ellipsis. **Hover:** Show full title.
  - **Genre**: Display `Categories - Sub`. Truncate with ellipsis. **Hover:** Show full text.
  - **Binding**: Display `Binding`.
  - **Condition**: Display `Condition` (e.g., "U - Like New").
  - **Publisher**: Display `Manufacturer`. Truncate with ellipsis. **Hover:** Show full text.
  - **Published**: Display `Publication Date`.
  - *(Separator / Sub-header)*: **Seller Details**
  - **Name**: Display `Seller`. Truncate with ellipsis. **Hover:** Show full text.
  - **Trust**: Display `Seller_Quality_Score` as "X / 10" (e.g., "10 / 10").

#### Group 2: Sales Rank (Supply & Demand)

- **Header:** "Sales Rank"
- Rows:
  - **Current**: `Sales Rank - Current` (Format: "4.5 M" or "289 k").
  - **180 Days Avg**: `Sales Rank - 180 days avg.`
  - **365 Days Avg**: `Sales Rank - 365 days avg.`
  - *(Separator / Sub-header)*: **Rank Drops**
  - **Last 180 Days**: `Sales Rank - Drops last 180 days`.
  - **Last 365 Days**: `Sales Rank - Drops last 365 days`.
  - *(Separator / Sub-header)*: **Used Offer Counts**
  - **Current**: `Used Offer Count - Current` + Trend Arrow (e.g., "1 ↗").
  - **Last 180 Days**: `Used Offer Count - 180 days avg.` + Trend Arrow.
  - **Last 365 Days**: `Used Offer Count - 365 days avg.` + Trend Arrow.

#### Group 3: Deal & Price Benchmarks

- **Header:** "Deal & Price Benchmarks"
- Rows:
  - **Now**: `Price Now` (Best Price).
  - **Shipping Included**: "Yes" or "No" (based on `Shipping Included` field).
  - **1yr Avg**: `1yr. Avg.` price. (**Confirmed:** This uses `get_1yr_avg_sale_price` which calculates the mean of *inferred* sales, not Keepa listing stats).
  - **% ⇩ Avg**: `% Down` (Percent discount vs 1yr Avg).
  - **Price Trending**: Directional Arrow (e.g., ↘) from `Trend` column.
  - **Updated**: Time since `last_price_change`. (**Confirmed:** This is the same data used in the "Ago" column on the dashboard).
  - **Amazon - Current**: `Amazon - Current` price. **Note: Leave blank if value is missing/None.**
  - **Amazon - 1yr Avg**: `Amazon - 365 days avg.` price. **Note: Leave blank if value is missing/None.**
  - **Buy Box Used - Current**: `Buy Box Used - Current` price. **Note: Leave blank if value is missing/None.**
  - **Buy Box Used - 1yr Avg**: `Buy Box Used - 365 days avg.` price. **Note: Leave blank if value is missing/None.**

#### Group 4: Listing & Profit Estimates

- **Header:** "Listing & Profit Estimates"
- Rows:
  - **Estimate Trust**: `Profit Confidence` (e.g., "80%").
  - **Profit**: `Profit` value. (**Confirmed:** Uses `List at` [Peak Price] - `All-in Cost`).
  - **Margin**: `Margin` value. (**Confirmed:** Uses `List at` [Peak Price] vs Cost).
  - **Max. List at**: `List at` price. (**Confirmed:** This is the Inferred Peak Price).
  - **Min. List at**: `Min. Listing Price`. (**Confirmed:** Uses `All-in Cost` / (1 - User Markup %)).
  - *(Separator / Sub-header)*: **Seasonality**
  - **Selling Season**: `Detailed_Seasonality` (e.g., "Law School").
  - **Est. Sell Date**: `Sells` column (e.g., "Nov - Jan"). (**Confirmed:** This is mapped from the Seasonality classification, which is derived from the inferred peak month).
  - **Est. Buy Date**: **Mapped from `Trough Season`**. (**Confirmed:** This is the inferred trough month collected in `stable_calculations.py`).
  - **Est. Buy Price**: `Expected Trough Price`. **Requirement:** This field is currently `None`. You must implement the logic to calculate it (Median price of the Trough Month) in `stable_calculations.py`.

### Styling Notes

- **Truncation:** Title, Genre, Publisher, and Seller Name must have a fixed max-width (approx 110px) and use `text-overflow: ellipsis`.
- **Hover:** Full text must appear on hover for truncated fields (same behavior as dashboard).
- **Formatting:** Follow the specific currency ($) and number formats (k/M) shown in the image.

## 2. Backend & Data Requirements

### A. Seasonality & Pricing Logic

1. **"Est. Buy Date":** Map this to the existing `Trough Season` field (calculated in `stable_calculations.py`).
2. "Est. Buy Price" (New Calculation):
   - In `stable_calculations.py` -> `analyze_sales_performance`:
   - Calculate the **Median** (or Mode) price of the identified `trough_month`, similar to how `peak_price_mode_cents` is calculated.
   - Return this value as `expected_trough_price_cents`.
   - Expose it in `processing.py` and `headers.json` as `Expected Trough Price`.

### B. Data Availability (`keepa_deals/processing.py` / `stable_products.py`)

1. Verify/Add Columns:

    

   Ensure the following fields are accurately calculated and populated in the database:

   - `Sales Rank - Drops last 180 days`
   - `Sales Rank - Drops last 365 days`
   - `Used Offer Count - 180 days avg.`
   - `Used Offer Count - 365 days avg.`

2. **Trend Calculation:** Ensure trend arrows (↗, ↘, →) can be derived for the 180-day and 365-day Offer Counts.

## 3. Implementation Steps

1. **Backend:** Implement `Expected Trough Price` calculation in `stable_calculations.py`.

2. **Backend:** Verify `180 days` metrics in `processing.py`.

3. Frontend:

    

   Edit

    

   ```
   dashboard.html
   ```

   .

   - Replace the existing modal structure with the 4-column grid.
   - Map the new JSON fields to the HTML.

4. Verification:

   - Verify the overlay matches the design.
   - Confirm "Est. Buy Date" displays the Trough Season.
   - Confirm "Est. Buy Price" displays the calculated trough price.
