# On a Field

> A playful personal-brand mark in the form of mock heraldry. Give up to three things you stand for, one to
> three everyday quirks and, optionally, an everyday object and a favourite colour. A metered grant picks a
> field tincture, an ordinary (the band across the shield) and a charge from a fixed vocabulary, ties each
> part to one of your own lines, and adds a short plain-English motto. The page draws the shield, writes the
> blazon itself, checks the rule of tincture (metal on colour, colour on metal) and lets you adjust the arms
> in a free workshop. Built on the SkillSafe skill @kostja94/branding.

## What is free
- The shield drawing, the workshop (field, band, charge, count, colours, motto), the blazon writer and the rule-of-tincture check all run in the browser.
- Three sample grants replay at no cost.
- Downloads: the shield (SVG, PNG), the arms with the grant's reasons (Markdown, JSON).

## The metered task
One task, `grant`, on gpt-terra, metered per run. The input is string fields: `task`, `holder`, `values` (numbered lines), `quirks` (numbered lines), `object`, `colour`, `colour_tincture` (worked out by the page) and `charge_count` (one per quirk). The reply is one JSON object: `headline`, `arms` {field, ordinary, ordinary_tincture, charge, charge_count, charge_tincture}, `blazon`, `reasons` (field, ordinary, charge - each quoting the line it came from), `motto` and `motto_from`.

Vocabulary: tinctures or, argent (metals) and gules, azure, vert, purpure, sable (colours); ordinaries none, fess, pale, bend, chevron, cross, saltire, chief; charges mullet, roundel, lozenge, crescent, heart, key, cup, book, tree, bell, anchor. The meanings the app gives them are its own playful key, not official symbolism.

Mock arms made for fun: not a grant from any heraldic authority and not the arms of any family.
