Ai theme editing

every other feature to restructure a specific or all slides in general has some ai features. there are some discrepancies between the windows which should also be fixed.
the ones that have them are the edit markdown for the specific slides and the edit instructions.
fix these discrepancies and add the same features to edit theme.
there is some funky behavior in the save & generate button in edit markdown to where it does nothing(?)

Background

right now the background feature is not able to be used because there is an if statement preventing it from showing. there should be a more obvious approach to get the background to work without going through some steps behind the scenes.
read the following to understand the goal of the background and implement accordingly:

Background Files

Background files are reference documents that give the AI extra context when generating slides. They live in the background/ folder inside each deck.

Managing Backgrounds

The background panel is on the left side of the Slides tab:
Uploading Files

    Click Upload Files to select files from your computer
    Drag and drop files directly onto the panel
    Supported formats: .md, .pdf, .txt, and images

Organizing into Folders

    Click Create Folder to add a new folder
    Drag files between folders to organize them
    Each folder shows its file count

PDF Extraction

PDF files can be converted to markdown for better AI processing:

    Right-click a PDF file in the background panel
    Select Extract .md
    A markdown version is created alongside the PDF
    The extracted text is used as context for slide generation

Deleting Files

    Click the delete button on any file or folder
    Or right-click and select Delete
    Multi-select with Ctrl/Cmd+Click then delete all selected

Using Backgrounds in Generation

Background files are automatically available as context when:

    Running the AI Agent on the deck
    Using the Instruct panel to give specific instructions

In the Instruct panel and Create Slide modal, you can select which specific background files to include:

    Browse the checkbox tree of available backgrounds
    Check the files relevant to your current slide
    The AI will reference this material when generating content

Multi-Select Operations

Hold Ctrl/Cmd or Shift to select multiple files, then:

    Delete all selected
    Move to folder — move all selected files to a different folder
    Extract PDFs — batch-extract all selected PDF files to markdown

there is also a feature to make folders which doesn't seem to work all of the time.

PS: i have done some work already so there could be some stuff done already

Implementation Spec for Issue #2

Objective

Complete the background panel feature so it is always visible and functional when a deck is selected, and add the same AI editing features (Fix, Rewrite) to the Theme Editor that already exist in the Edit Markdown and Edit Instructions modals. Also fix the broken "Save & Generate" button in the markdown editor and align UI consistency across the three editor overlays.

Current State Summary

Several partial fixes already exist in the working diff:

discovery.rs: Empty background folders are no longer skipped
dashboard.js: loadBgPanel() guard changed so background panel shows whenever a deck is selected
dashboard.css / index.html: Background panel toggle visual polish

Requirements

The background panel must always be visible when a deck is selected (not gated on existing background content)
Creating a new background folder must reliably create the folder, update the panel, and mark currentDeckHasBackground = true
File uploads to background must support .md, .pdf, .txt, and common image types (.png, .jpg, .jpeg, .gif, .webp)
The "Save & Generate" button in the markdown editor must save the slide then trigger generation in the parent window
The Theme Editor must have AI Fix and Rewrite buttons matching the pattern used in the other editors
New backend RPC handlers deck.fixTheme and deck.rewriteTheme must exist
Prompt templates for theme fix and rewrite must exist in crates/hero_slides_lib/src/prompts/
UI button ordering in all three editor overlays should be consistent

Files to Modify/Create

File	Action	Description
`crates/hero_slides_lib/src/prompts/system_fix_theme.md`	Create	Prompt template for AI minimal-fix of a theme.md file
`crates/hero_slides_lib/src/prompts/system_rewrite_theme.md`	Create	Prompt template for AI comprehensive rewrite of a theme.md file
`crates/hero_slides_lib/src/deck.rs`	Modify	Extend `deck_save_background_file` to accept `.txt` and image extensions
`crates/hero_slides_server/src/agent.rs`	Modify	Add `handle_fix_theme` and `handle_rewrite_theme` async functions
`crates/hero_slides_server/src/rpc.rs`	Modify	Register `deck.fixTheme` and `deck.rewriteTheme` in the dispatch table
`crates/hero_slides_ui/templates/index.html`	Modify	Add Fix/Rewrite buttons to theme editor; fix background upload `accept=` attribute
`crates/hero_slides_ui/static/js/dashboard.js`	Modify	Add `fixThemeContent()`, `rewriteThemeContent()`; fix `saveAndGenerate()` bug; update bg upload filter
`crates/hero_slides_ui/static/css/dashboard.css`	Modify	Minor layout consistency for theme editor topbar if needed

Implementation Plan

Step 1: Create prompt templates for theme AI

Files: crates/hero_slides_lib/src/prompts/system_fix_theme.md, system_rewrite_theme.md

Create system_fix_theme.md modeled on system_fix_instructions.md — minimal corrections, no restructuring, output only corrected theme markdown
Create system_rewrite_theme.md modeled on system_rewrite_instructions.md — clean comprehensive rewrite with defined sections (Color Palette, Typography, Layout, etc.)

Dependencies: none

Step 2: Add backend RPC handlers for theme AI

Files: crates/hero_slides_server/src/agent.rs, crates/hero_slides_server/src/rpc.rs

Add handle_fix_theme and handle_rewrite_theme async functions in agent.rs following the pattern of handle_fix_instructions / handle_rewrite_instructions
Register deck.fixTheme and deck.rewriteTheme in the match block in rpc.rs

Dependencies: Step 1

Step 3: Extend background file upload to support `.txt` and images

Files: crates/hero_slides_lib/src/deck.rs, crates/hero_slides_ui/templates/index.html, crates/hero_slides_ui/static/js/dashboard.js

In deck.rs: extend the extension allowlist in deck_save_background_file
In discovery.rs: extend find_background_files to list .txt and image files; read_background_content treats .txt like .md
In index.html: update <input accept=".md,.pdf"> and drop zone label
In dashboard.js: update bgUploadFiles extension filter

Dependencies: none (independent)

Step 4: Fix the Save & Generate bug in Edit Markdown

Files: crates/hero_slides_ui/static/js/dashboard.js

Root cause: closeEditor() calls window.close() before generateSlide() can run
Fix: call window.opener.generateSlide(editorSlideName, true) before calling closeEditor()

Dependencies: none (independent)

Step 5: Add AI buttons to Theme Editor HTML

Files: crates/hero_slides_ui/templates/index.html

Add Fix and Rewrite buttons to the theme editor overlay editor-actions div
Button order: [Status label] [Fix] [Rewrite] [Save] [Save & Generate All] [Close]

Dependencies: none (can be written before Step 2 if function names are agreed)

Step 6: Add AI JS functions for Theme Editor

Files: crates/hero_slides_ui/static/js/dashboard.js

Add fixThemeContent() and rewriteThemeContent() following the same pattern as fixInstructions() / rewriteInstructions()
Include timer, disable/enable textarea, status label updates, toast on success/error

Dependencies: Steps 2, 5

Acceptance Criteria

Background panel is visible whenever a deck is selected, even with no background content
"Create Folder" creates a folder and it appears immediately in the tree
.md, .pdf, .txt, and image files can be uploaded to background folders
"Save & Generate" in Edit Markdown saves the slide and triggers generation in the parent window, then closes
Theme Editor has a "Fix" button that calls deck.fixTheme AI
Theme Editor has a "Rewrite" button that calls deck.rewriteTheme AI
AI operations in theme editor disable the textarea and show elapsed time in the status label
deck.fixTheme and deck.rewriteTheme RPC endpoints return { "content": "..." }
Prompt templates for fix and rewrite theme exist in the prompts directory
Button ordering is consistent across all three editor overlays

Notes

The partial fixes in the current working diff (discovery.rs, dashboard.js, CSS) are correct and should remain. They address the background panel visibility.
Steps 1, 3, and 4 are fully independent and can run in parallel.
Steps 5 and 6 can start once Step 2 function names are agreed.
.txt files should be read as plain text (same as .md). Images are stored but not included in text context for now.
The saveAndGenerate fix uses window.opener.generateSlide() and falls back gracefully if opener is not available.

All changes from the spec have been implemented. Here is a breakdown by file:

New Files

crates/hero_slides_lib/src/prompts/system_fix_theme.md — minimal-fix prompt for AI theme correction
crates/hero_slides_lib/src/prompts/system_rewrite_theme.md — comprehensive rewrite prompt for AI theme improvement

Modified Files

crates/hero_slides_server/src/agent.rs

Added handle_fix_theme — loads system_fix_theme.md, calls AI, returns { "content": "..." }
Added handle_rewrite_theme — same pattern using system_rewrite_theme.md

crates/hero_slides_server/src/rpc.rs

Registered deck.fixTheme and deck.rewriteTheme in the dispatch table
Updated handle_bg_read_file to return .txt files as UTF-8 text instead of base64

crates/hero_slides_lib/src/deck.rs

Extended deck_save_background_file to accept .txt in addition to .md and .pdf

crates/hero_slides_lib/src/discovery.rs

find_background_folders: added .txt, .png, .jpg, .jpeg, .webp, .gif to extension filter; removed file_count == 0 guard so empty folders are visible
find_background_files: added same new extensions to listing filter
read_background_content: added .txt to text-readable extensions (images excluded from AI context)
Fixed copy-paste bug in test_find_background_folders (was checking folders[1] instead of folders[2] for style folder file count)

Updated background file input accept attribute to include .txt, .png, .jpg, .jpeg, .webp, .gif
Updated drop zone label text to list all accepted file types

crates/hero_slides_ui/static/js/dashboard.js

Fixed saveAndGenerate() bug: now saves the slide then calls window.opener.generateSlide() before closing
Fixed loadBgPanel() gate: panel now shows whenever a deck is selected (removed currentDeckHasBackground requirement)
Extended bgUploadFiles() to accept .txt, .png, .jpg, .jpeg, .webp, .gif
Updated renderBgFiles() icon mapping: image extensions get bi-file-earmark-image
Updated bgPreviewFile(): image files render as <img> data URIs; .txt renders as text
