+ * 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.

+ 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()`.
+

 # Cappuccino: Build Desktop-Class Web Applications
 
-> **🛑 Legacy Branch: Node.js Tombstone**
-> This branch is the final, unmaintained state of the pre-Aristo3 Node/npm era (tagged `v1.4.0`), remaining visually and mechanically compatible with the `1.3.1` npm release. Bug fixes and improvements from the main branch are included. It uses Aristo2 as its theme.
-> 
-> While the main branch is intended to maintain backward theme and toolchain compatibility, no guarantees are made that this branch will be advanced in sync with it. This branch is intended solely as a frozen artifact for those requiring an extended transition period to Cappuccino 2.
+> **✨ Project Status: v1.5.0 Baseline & Upcoming v2.0.0 Toolchain**
+>
+> 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.**

 ## 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: 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.
