Please help me install and set up "Coral" from veered.org on my own computer or server.

What it is: Patent flowchart maker: a description, a claim or the full claim set in, a filing-ready decision flowchart out. It runs on: Any web browser: nothing to install, and the chart never leaves your computer.

How I'd like you to help:
1. First ask me what you need to know: my operating system and version, my desktop environment if it matters, whether I'm comfortable with the terminal, and any accounts or hardware this project needs.
2. Then take me through it one step at a time. For each command, say briefly what it does, and wait for me to paste back the result before moving on.
3. Before any step that changes system settings, uses sudo, or edits an existing configuration file, tell me, and have me make a backup first.
4. If something fails, help me work out why. If the instructions below don't fit my system, say so rather than guessing.
5. At the end, show me how to check that it works, and how to uninstall it.

The project is shared as-is by its author, with no warranty. If we find a problem in the project itself, please help me write a short, clear note I can send to support@veered.org.

# Patent Flowchart Maker (Coral): steps in, filing-ready flowchart out

Coral turns a description, a claim, or a full claim set into a decision flowchart. Describe what the thing does, paste claims, type the steps, or write an indented outline; the tool places every shape and arrow, checks the sheet against the USPTO drawing rules (37 CFR 1.84), and exports a PDF with embedded fonts, an SVG, or a PNG at 300 or 600 dpi. A second preset makes the same chart for a website or a presentation.

**Try it:** open `index.html` from any web server (`python3 -m http.server`). Nothing is uploaded; charts are kept in the browser and in the project files you save.

## What it does
- **Describe or paste:** type what the process does in plain sentences, or paste one claim or the whole claim set, and press Make the flowchart.
  - A description becomes steps; "If …, …; otherwise, …" becomes a decision with both branches; "go back to …" becomes a loop.
  - A claim set gives one figure per independent method claim. Dependent claims are folded in: "further comprising" adds steps, and a "wherein" clause becomes a sub-step of the step it limits. "Determining whether …" becomes a diamond, and "in response to determining that …" becomes its Yes or No branch. Claim wording is kept, and no numerals are added.
  - Optionally, Claude drafts the chart instead (tick the box and paste your own Anthropic API key). The text then goes to Anthropic under your key; otherwise nothing leaves the browser.
- **Steps:** add, edit, delete, reorder (buttons or drag), indent and outdent. Each step has its own shape: rectangle, rounded rectangle, diamond, oval, terminator, parallelogram, hexagon, circle.
- **Decisions:** a step ending in `?` becomes a diamond; the rows indented under it are its branches (Yes / No, or any number of outcomes).
- **Loops:** `-> 102` sends the flow back (or ahead) to step 102, routed around the chart on the side with the fewest crossings.
- **Start / End** terminators, and **off-page connectors**: type `(A)` to continue on another sheet, or let a long chart break by itself onto circled letters.
- **Sub-steps:** rows indented under a step are drawn as boxes inside it.
- **Style:** typeface, size, alignment, line weights, box padding and width, spacing, arrow line (straight, elbow, curved), solid or dashed, arrowhead shape and size, margins, paper. Save any combination as a preset; "USPTO formal" and "Website/presentation" are built in.
- **Figures:** several figures per project; "Duplicate figure" copies one as the start of the next and asks for the new figure number.
- **Detailed Description text:** starter sentences written from the chart with the numerals you chose ("At step 104, the method determines…").
- **Undo / redo**, autosave, project files (`.json`).

## USPTO compliance mode (on by default)
| Rule | What the tool does |
|---|---|
| Margins, 1.84(g) | One click sets top 2.5 cm, left 2.5 cm, right 1.5 cm, bottom 1.0 cm; smaller margins are flagged |
| Paper, 1.84(f) | Letter or A4 only |
| Black and white, 1.84(a)(1), (m) | No color, fill or shading |
| Lettering, 1.84(p)(3) | The size control stops where capitals are 0.32 cm high (13.5 pt in Liberation Sans) |
| View label, 1.84(u) | "FIG. X" with the X you type; a chart on several sheets gets 3A, 3B (editable) |
| Reference numerals, 1.84(p) | You type each numeral; the tool never assigns or renumbers them, and flags a numeral used twice |
| Sheet numbers | None added |

The checker lists every violation beside the drawing and again before an export. Switch compliance mode off to lift the limits.

## Outline format
```
Start
102: Receive a sign-in request
104: Is the password correct?
    Yes:
        106: Create a session token
    No:
        108: Count the failed attempt
        -> 102
110: Send the response {parallelogram}
End
```

## Files
`engine.js` (parsing, layout, routing, checks, description text; no DOM, `node tests/engine.test.js`), `export.js` (PDF through [pdf-lib](https://pdf-lib.js.org/), PNG through canvas), `app.js` (the page), `fonts/` (Liberation Sans, Serif and Mono, and Lexend, embedded in the PDF because Patent Center rejects fonts that are not embedded).

## What it is not
It is not legal advice, and the checker covers the rules above, not all of 37 CFR 1.84. Review every drawing before filing.

## Name
Coral: a red that grows by branching.

Download https://veered.org/patent-flowchart-maker/coral-patent-flowchart-maker.zip, unzip it into a new folder, read every README.md in it, and help me install and set up "Coral" (Patent flowchart maker: a description, a claim or the full claim set in, a filing-ready decision flowchart out) on this machine. Check the requirements against this system first and tell me what is missing. Ask me before running anything with sudo, installing packages, or changing existing configuration files, and back those files up first. Finish by showing me how to test it and how to uninstall it.
