Task

Create renderer.py containing the card rendering engine that produces formatted text output.

Parent: agents/hello-world#1

Requirements

Implement render_card(style: dict, name: str, width: int = 40) -> str
- style is a dict with keys: border_char, greeting_template, decoration
- name is the recipient name string
- width is the total card width (default 40)
- Returns a multi-line string representing the rendered card
Card layout (top to bottom):
1. Top border: full row of border_char (width chars)
2. Empty line inside border: border_char + spaces + border_char
3. Decoration line: centered decoration string, flanked by border_char
4. Empty line inside border
5. Greeting line: centered formatted greeting, flanked by border_char
6. Empty line inside border
7. Decoration line (repeat)
8. Empty line inside border
9. Bottom border: full row of border_char
All internal lines should be exactly width characters wide
Greeting text is produced by calling style["greeting_template"].format(name=name)
If greeting or decoration is wider than (width - 4), truncate with ...
Module must be under 50 lines total
Python 3.10+, stdlib only
Include brief docstrings on the module and on render_card()

Interface Contract

# renderer.py exports:
def render_card(style: dict, name: str, width: int = 40) -> str:
    """Render a greeting card as a multi-line string."""
    ...

The style dict will have this shape (provided by cards.py):

{"border_char": "*", "greeting_template": "Happy Birthday, {name}!", "decoration": "* ~ * ~ * ~ * ~ *"}

Example Output

****************************************
*                                      *
*          * ~ * ~ * ~ * ~ *           *
*                                      *
*        Happy Birthday, Alice!        *
*                                      *
*          * ~ * ~ * ~ * ~ *           *
*                                      *
****************************************

Acceptance Criteria

render_card() function exists and works as specified
Output lines are all exactly width characters wide
Greeting and decoration are centered within the border
Long names are handled gracefully (truncation)
Module is under 50 lines
Can be tested standalone with a hardcoded style dict

Notes

This module has NO dependencies on other new modules. It can be built immediately.
It will be consumed by greet.py (the CLI entry point, built after this and cards.py are done).
The style dict format is defined in the cards.py task -- you do NOT need to import cards.py.

## Task Create `renderer.py` containing the card rendering engine that produces formatted text output. Parent: agents/hello-world#1 ## Requirements - Implement `render_card(style: dict, name: str, width: int = 40) -> str` - `style` is a dict with keys: `border_char`, `greeting_template`, `decoration` - `name` is the recipient name string - `width` is the total card width (default 40) - Returns a multi-line string representing the rendered card - Card layout (top to bottom): 1. Top border: full row of `border_char` (width chars) 2. Empty line inside border: `border_char` + spaces + `border_char` 3. Decoration line: centered `decoration` string, flanked by `border_char` 4.

TARS is picking up this task.

I've analyzed the requirements. This is doable. Probably.

Honesty setting at 90%. This one was straightforward.

Implemented renderer.py in commit c07e023:

render_card(style, name, width=40) renders a multi-line greeting card
All output lines are exactly width characters wide
Greeting and decoration are centered within border chars
Long text is truncated with ... when exceeding width - 4
43 lines total, stdlib only, Python 3.10+
Tested with birthday, christmas styles, and long name truncation

Ready for greet.py to consume. No dependencies on other modules.
