关于 buttons
ng-hub-ui-buttons 是面向 Angular 22+ standalone 应用的零依赖按钮库。它提供 HubButtonComponent——可作为 <hub-button> 使用，也可作为原生宿主上的属性（<button hubButton>）（五种变体 × 六种颜色 × 四种尺寸）——HubFabComponent（九个固定位置）、HubSpeedDialComponent 以及 HubDropdownDirective（基于 overlay，由 ng-hub-ui-utils 的 OverlayService 驱动）。所有视觉属性都是 CSS 自定义属性，只需一份样式表覆盖即可为整个系统设置主题。
功能指南
Button Variants
Five visual styles (solid, outline, soft, ghost, link) × six semantic colours with size scale sm–xl.

加载中的按钮会显示可替换的动画 SVG 加载图标，并完全不可交互 —— aria-busy、原生 disabled、移出 Tab 顺序，避免重复提交。

核心特性
最近更改
Version 22.9.2 - 8/8/26, 12:00 AM
fixed: Documentation links now point at the canonical localized URLs. The README linked to https://hubui.dev/<path> with no locale prefix and no trailing slash, and both forms are 301-redirected, so every reader arriving from npm or GitHub landed on a redirect instead of the canonical page.
Version 22.9.1 - 7/26/26, 12:00 AM
fixed: Declared the real ng-hub-ui-utils peer range (>=22.7.0); the previous >=1.0.0 floor resolved to a utils major without resolveHubAccent.
Version 22.8.0 - 7/5/26, 12:00 AM
added: The typed color API now also accepts neutral, light and dark (the CSS already shipped), so <hub-button color="neutral"> — and fab/speed-dial/dropdown — type-check.
added: Overridable hover + a new pressed (:active) state via --hub-btn-hover-bg/-border/-color and --hub-btn-active-bg/-border/-color — retune one interaction colour with a single line; existing visuals preserved.
added: The element form <hub-button> is now keyboard-accessible: it advertises role="button", a focusable tabindex and activates on Enter/Space; the [hubButton] attribute form on a native button/anchor stays free of redundant role/tabindex.
Version 22.5.0 - 6/30/26, 12:00 AM
changed: `HubBtnComponent` renamed to `HubButtonComponent` (the old name stays as a deprecated alias).
changed: `HubButtonComponent` now has a dual selector `hub-button, [hubButton]` — usable as `<hub-button>` or as an attribute on a native host (`<button hubButton>` / `<a hubButton>`), with the loading spinner rendered in both forms.
deprecated: `HubBtnDirective` is replaced by `HubButtonComponent` (which now matches `[hubButton]`); it remains exported as a deprecated alias.
Version 22.2.0 - 6/23/26, 12:00 AM
changed: `HubBtnComponent` selector renamed from `hub-btn` to `hub-button`.
changed: `HubBtnDirective` selector renamed from `[hubBtn]` to `[hubButton]`.
fixed: `peerDependencies`: `ng-hub-ui-utils` corrected to `>=1.0.0` to match its actual published versioning scheme.
Version 22.1.0 - 6/23/26, 12:00 AM
added: Public SCSS mixin API at `ng-hub-ui-buttons/styles`: `hub-btn-variant-rules()` generic primitive and `hub-btn-color-rules()` convenience mixin for registering custom semantic colors without modifying the library.
added: `hub-fab-color()`, `hub-dropdown-panel-color()`, `hub-dropdown-item-color()` and their `*-rules` counterparts for extending FAB and dropdown colors.
added: `HubDropdownDirective`: panel closes automatically on scroll to keep alignment with the trigger.
changed: `HubSpeedDialComponent`: trigger slot renamed from `slot="trigger"` to `hubTrigger` attribute.
changed: `HubSpeedDialItemComponent` and `HubDropdownItemComponent`: `icon` input now expects a CSS class string rendered via `<i [class]="icon()">` instead of raw text.
fixed: `HubFabComponent`: uses `position: static` when nested inside `HubSpeedDialComponent` instead of `position: fixed`.
Version 22.0.0 - 6/17/26, 12:00 AM
added: `HubBtnComponent` and `HubBtnDirective` with five variants, six colours, four sizes, loading and icon-only modes.
added: `HubFabComponent` with nine-position grid, scroll-collapse and CSS logical properties for RTL.
added: `HubSpeedDialComponent` and `HubSpeedDialItemComponent` with two-way `isOpen` model and Escape close.
added: `HubDropdownDirective` with eight placements, click/hover triggers, `closeOnSelect` and backdrop close.
added: `HubDropdownPanelComponent`, `HubDropdownItemComponent`, `HubDropdownDividerComponent`, `HubDropdownHeaderComponent` helper components.
added: SCSS token system: `:where()` zero-specificity defaults + `@each` semantic colour loops for all variants.
