+ * PLACEHOLDER IMPLEMENTATION — READ BEFORE USE OR MODIFICATION.
+ *
+ * This class lays out views by direct, procedural arithmetic. It has no
+ * constraint solver. It cannot compress, expand, or negotiate space among
+ * views the way NSStackView does; it only places views at their existing
+ * frame size, in order, separated by fixed spacing.
+ *
+ * Known, accepted limitations:
+ *   - `distribution` is stored but has no effect on layout. Fill,
+ *     FillEqually, FillProportionally, and EqualSpacing are unimplemented.
+ *   - Center-gravity views are clamped against the Leading edge only; if
+ *     Leading + Center + Trailing content overflows the container, Center
+ *     views can overlap Trailing views instead of compressing.
+ *   - `visibilityPriority:forView:` only supports the two extreme values
+ *     (MustHold / NotVisible). Intermediate priorities are accepted but
+ *     have no defined effect.
+ *   - No guarantee is made of correctness beyond what a single manual
+ *     test (Tests/Manual/CPStackViewTest) exercises: orientation, the
+ *     three gravity areas, alignment switching, spacing, and hidden-view
+ *     detachment. Insertion, removal, custom spacing, and the CPCoding
+ *     archive path are implemented but not verified by that test.
+ *
+ * This exists to give AppKit a working CPStackView symbol now, not to be
+ * a durable design. It is expected to be replaced by a constraint-solver
+ * based implementation (Kiwi.js) when time permits. Do not build on its
+ * internal layout algorithm as if it were a stable foundation.

+ Objective-J is a strict superset of JavaScript and compiles down to a shared global runtime scope.
+ This file (_CPFoundationUtilities.j) is the canonical place for otherwise "homeless" low-level
+ utilities, stateless helpers, and former C-style preprocessor macros that do not belong to a
+ specific class but are required across the framework.
+
+ While modern JavaScript ecosystems (e.g., ES6 modules, bundlers) treat the global scope as something
+ to be strictly avoided, Cappuccino's architecture predates these paradigms. It relies entirely on
+ global scope sharing for its runtime and toll-free bridging with native JavaScript, much like C and
+ Objective-C. Therefore, injecting `CP`-prefixed functions into the global scope is the intended design
+ pattern here, not an anti-pattern or "pollution."
+
+ ----------------------------------------------------------------------------
+ New compiler does not provide a pre-processor.
+ The macro is expanded here to a concrete function.
+
+ The alternative is inlining at call site.
+ On a cold call, this provides a very minor performance advantage.
+ Conversely, it provides the Javascript engine fewer opportunities to optimize,
+ which is only done when a call site is invoked.
+ Additionally, it depends on individual maintainers to correctly implement the call every time.
+
+ The macro is expanded here precisely to maintain identical semantics.
+
+ Every current, popular browser engine optimizes a small, hot, monomorphic function like a numeric check almost immediately:
+
+ V8 (Chrome, Edge, Opera, Brave, Node) — tiered JIT (Ignition → Sparkplug → Maglev → TurboFan).
+ A function called this often gets promoted within tens of calls.
+ SpiderMonkey (Firefox) — Baseline Interpreter → Baseline JIT → Ion. Same pattern.
+ JavaScriptCore (Safari, all iOS browsers, since iOS forces WebKit) — LLInt → Baseline → DFG → FTL.
+
+ All three engines specialize aggressively on exactly this shape of code: a tiny, pure, argument-type-stable function with no side effects. It is close to the ideal case for JIT optimization — the compiler will likely inline the call at the machine-code level, which is the same outcome as hand-inlining the expression, achieved automatically.
+
+ There is no browser in current popular use — desktop or mobile — where this function call would remain a meaningful cost.
+ Additionally, modern hardware and Javascript engines are so much faster than in 2008, when Cappuccino was conceived,
+ that even a cold execution of this function is trivial.
+ The performance objection which originally required in-lining via a macro does not exist for current targets.
+
+ Javascript, Objective-J, C, and Objective-C all lack native namespacing.
+ 'CP' is the canonical namespace prefix used throughout Cappuccino to address potential collisions.
+ It is reserved by convention.

+ numbers and strings that can be successfully parsed into a finite number (e.g., 42, "3.14"),
+ and false for NaN, Infinity, null, and purely non-numeric strings.
+
+ This specific logic (parseFloat + global isFinite) is deliberately preserved to prevent
+ regressions in code that historically relied on its lenient string parsing, rather than
+ using the stricter modern ES6 `Number.isFinite()`.
+
+ TODO: Modernize this check to use ES6 `Number.isFinite()`. This is currently deferred

+> Cappuccino has been under continuous development since 2008 and is actively maintained. The v1.5.0 release establishes a baseline as we move to the new resolution-independent Aristo3 theme and Go-based toolchain.
 
 > For users seeking a complication-free alternative who wish to avoid the Aristo3 work entirely, the legacy-1.4.0 branch provides an unambiguous freeze point. Please note, however, that this legacy branch is not guaranteed to receive any future bug fixes or improvements.
 
 > Active development is now focused on the upcoming v2.0.0 release, which will transition the full toolchain to Golang and the platform-native binaries it produces, leaving Node.js and npm behind.
 
+> **🚨 Aristo3 Theme: Community Testing Required**
+>
+> Aristo3 represents a non-trivial refactoring of AppKit UI classes. While unit tests pass, it must be tested against real-world applications before being merged into `main`. Community members testing against their own applications will accelerate the process. We are not concerned with minor visual breakages or cosmetic regressions at this stage; **the primary concern is structural failures.**
+>
+> The fully merged state has been pushed to the `aristo3` branch on the canonical repo.
+>
+> **How to help:**
+> 1. Check out the `aristo3` branch: `git fetch origin && git checkout aristo3`
+> 2. Build the frameworks and run your existing applications against this branch.
+> 3. Open your browser's developer console and watch for:
+>    - Uncaught `CPException`s or JavaScript errors.
+>    - Infinite layout loops (browser freezing/tab crashing).
+>    - Broken responder chains or keyboard event handling.
+>    - KVO/Binding failures or `valueForThemeAttribute:` resolving to `nil` unexpectedly.
+>    - View hierarchy corruption (subviews disappearing or failing to clip).
+>
+> Please leave a 👍 on the [Aristo3 Pull Request](https://github.com/cappuccino/cappuccino/pull/3038) if your apps run without structural failures. If you encounter exceptions or crashes, please leave a comment with the stack trace. **A solid response of thumbs up is required before `main` can be merged. Our intention is to leave no community member behind.**

 ## Why Use Cappuccino?
 
 Cappuccino is for building **applications** in the browser — especially complex, data-rich, line-of-business tools where productivity and user experience are paramount. Instead of direct manipulation of HTML, CSS, and the DOM, applications are built using Objective-J, a superset of JavaScript modeled on Objective-C. This gives you a lot of benefits:

 ## Frequently Asked Questions (FAQ)
 
-**Q: What are the advantages over React or Vue?**  
+**Q: What are the advantages over React or Vue?**
 **A:** React and Vue are excellent libraries for building web UIs. Cappuccino is a comprehensive **framework** for building entire **applications**. It provides a fully integrated stack—including a mature UI library, event handling, and data management—designed for large-scale development.
 
 Beyond this, Cappuccino provides a more integrated and powerful data-binding layer inspired directly by Cocoa, which dramatically reduces boilerplate code for complex UIs as you can see in this [example code](https://github.com/daboe01/UIBuilder/tree/master/public/Frontend) that uses these features:

 *   **Advanced Filtering with Predicates:** A table displaying thousands of items can be filtered simply by setting a predicate (a declarative filter rule, e.g., `lastName BEGINSWITH 'S'`) on its controller. The UI updates instantly. This eliminates tons of manual state management and filtering logic code.
 *   **Automatic Value Transformation:** Data can be easily formatted for display (e.g., dates, currency, booleans to "Yes/No") directly within the binding itself using value transformers, keeping model data pure and view logic minimal.
 
-**Q: Can Cappuccino be used on Windows/Linux?**  
+**Q: Can Cappuccino be used on Windows/Linux?**
 **A:** Yes. The development tools run on Node.js and are platform-independent. Applications can be developed on any OS and deployed on any web server.

+**Q: Is Xcode required?**
 **A:** No. Any code editor can be used. Xcode offers optional visual development tools for macOS users, but it is not a requirement.

+**Q: Hasn't Apple moved on from Objective-C, making these APIs obsolete?**
 **A:** While Swift is Apple's newer language, Objective-C and AppKit remain foundational, actively supported technologies used in many of Apple's flagship applications. Cappuccino leverages the stability and power of this time-tested API design, which is independent of Apple's future product roadmap.

+**Q: How can custom HTML, CSS, or JavaScript libraries be integrated?**
 **A:** Cappuccino abstracts away the DOM, but other web technologies can still be integrated. The `CPWebView` control allows arbitrary HTML/CSS/JS content to be embedded. Since Objective-J is a superset of JavaScript, JS libraries can be used and JS functions can be called directly from Objective-J code.
