Merge branch 'master' into colour-improvements

Calls stated that a value needs no delimiters if it contains no spaces or
quotes. A colon also requires them: name:value is call syntax, so the text
before the colon is read as a parameter name and the positional parameter
receives nothing, silently.

Call Syntax already has this right - param-name ":" value is one of its
productions - so this brings the prose into line with the grammar, and adds
a warning naming the two ways round it.

-# Repository Contribution Guidelines & Automation
-
-This document establishes the single source of truth for repository contribution guidelines, optimized for AI context consumption, alongside a TiddlyWiki-based automation strategy to prevent source-of-truth drift.
-
----
-
-## 📄 The High-Density Ruleset
-*Copy the content below into a single master tiddler titled `ProjectContributionRules` with the type `text/x-markdown`.*
-
-```markdown
-# CONTRIBUTING
-
-## AI & Comment Rules
-* Banned: Conversational filler, verbose explanations of standard APIs, or teaching basic programming logic.
-* Required: Prune all AI-generated comment blocks down to a single sentence maximum.
-* Focus: Comments must only state the "why" behind non-obvious engineering decisions, never the "how".
-* PR Descriptions: Write concise, bulleted summaries of what changed. Do not use AI-generated marketing/polite filler text.
-
-### Code Comment Examples
-* BAD: // Use behavior:"instant" so that this animation's per-frame position updates are applied immediately and are NOT re-animated by a CSS `scroll-behavior: smooth` on the scrolling element (which would make the page lag behind and stutter).
-* GOOD: // Use 'instant' to prevent conflicts with CSS scroll-behavior: smooth.
-
-## Workflow Rules
-* Branching: Base all feature branches on `main`. Use `feat/` or `fix/` prefixes.
-* Scope: Keep pull requests limited to a single logical change. Massive, multi-feature PRs will be rejected.
-* Testing: Run local tests and formatting checks before pushing.
-* Merging: All commits are squashed on merge.
-```

-## 🛠️ TiddlyWiki Build Integration
-To ensure this file is distributed automatically to all required locations without duplication, use TiddlyWiki's native command-line rendering tool.
-
-### 1. Update `tiddlywiki.info`
-Add a dedicated `repo-configs` target to your project's `tiddlywiki.info` JSON file. This instructs TiddlyWiki to compile the master tiddler out to both human-facing and AI-facing configuration endpoints:
-
-```json
-{
-    "description": "Project build targets",
-    "plugins": [
-        "tiddlywiki/markdown"
-    ],
-    "build": {
-        "repo-configs": [
-            "--rendertiddler", "ProjectContributionRules", "./CONTRIBUTING.md", "text/plain",
-            "--rendertiddler", "ProjectContributionRules", "./.claudecode", "text/plain"
-        ]
-    }
-}
-```
-
-### 2. Update `package.json`
-Integrate the rendering command into your existing Node.js project lifecycle scripts so it triggers automatically during development builds or pre-commit checks:
-
-```json
-{
-  "scripts": {
-    "build:configs": "tiddlywiki --build repo-configs"
-  }
-}
-```
-
----
-
-## 🚀 Why This Works
-* **Zero Duplication:** Edits are made exclusively within `ProjectContributionRules` inside the wiki workspace.
-* **Human Visibility:** Browsing GitHub automatically surfaces `CONTRIBUTING.md` to human contributors.
-* **Claude Code Ready:** When **Claude Code** sweeps the project root, it instantly reads the identical, strict engineering boundaries outputted to `.claudecode`.
