kevinveenbirkenbachandClaude Opus 4.7 16bdbf03d7 docs: fix repo-wide drift against documentation.md style rules
Three classes of drift cleaned up across 85 .md files:

- Em-dashes: replaced ` — ` with the contextually correct separator
  (colon for `term: explanation`, period to split clauses across
  sentences/source lines, parentheses for asides, semicolon for
  tight-linked continuations). Two intentional exceptions remain
  in `docs/contributing/documentation.md` (the rule literal) and
  inside a fenced ```sh block in `docs/contributing/actions/debugging/ci.md`.
- SPOT self-labels: rewrote "This is the SPOT for X" to describe
  the subject directly ("This directory holds X" / "This file
  describes X"). Cross-references to other artefacts' canonical
  role remain unchanged.
- Heading-emoji position: moved leading-emoji headings (`# 🧩 Title`)
  to trailing position (`# Title 🧩`) per the headline rule that
  emojis MUST come after the title text.

# Shell
## Description
This Ansible role ensures that [.profile](https://en.wikipedia.org/wiki/Bourne_shell#Startup_scripts) is sourced in both [Bash](https://www.gnu.org/software/bash/) and [Zsh](https://www.zsh.org/) environments. It enables consistent environment variable loading across different login shells by linking shell-specific profile files (`.bash_profile`, `.zprofile`) to a centralized `.profile`.
## Overview
By standardizing `.profile` as the central source for environment configuration, this role ensures consistent shell behavior. It does **not** manage the contents of `.profile` itself; it only guarantees that it is sourced by supported shells.
## Purpose
The purpose of this role is to unify shell environment setup across Bash and Zsh. It minimizes duplication and confusion by encouraging the use of `.profile` for shared configuration such as environment variables and agent settings.
## Features
- **Centralized Configuration:** Promotes `.profile` as the single source for shared shell settings.
- **Cross-Shell Compatibility:** Ensures both Bash and Zsh source `.profile` properly.
- **Non-Invasive:** Does not alter the content of `.profile`.
