From c00bac13450b6a30004fe6dfcee1a665e7d0cf16 Mon Sep 17 00:00:00 2001 From: dev Date: Mon, 22 Jun 2026 21:31:58 +0200 Subject: [PATCH] =?UTF-8?q?feat(eidos):=20action=20components=20=E2=80=94?= =?UTF-8?q?=20fab,=20onion-menu,=20button-group,=20split-button?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Ship the four action-cluster components. Per the audit the user requested, the hardcoded magic numbers in their CSS move to recipes (base.ts), so the values live in one place and pass the recipe-CSS contract: - fab: the off-ladder Material size / icon / lift scale → `fab` recipe (named tokens — the canonical control-height / icon-size ladders genuinely can't express 40/56/72 + 20/24/28; documented as the FAB's own scale). - onion-menu: the radial-chrome magics (sector ring widths, glyph bar, trail opacities) → `onion-menu` recipe; the centre trigger's lift + shadow REFERENCE `--fab-*` (it IS a FAB — the two can't drift apart). - button-group: the segmented-divider strength → `button-group` recipe. - split-button: the slim chevron tail's inline padding → `split-button` recipe; DropdownMenu gains `customAnchor` so the menu spans the whole split surface. All four compose the framework primitives (Group / Button / Icon / DropdownMenu), declare a morfo, ship langs + a demo, and pass the recipe-CSS contract test (the only flagged component left is palabras, an active dev track). check 0; onion-menu engine tests 31/31.

color'primary' | 'secondary' | 'neutral''primary'Hierarchical color propagated to child Buttons. Per-button intent is set on the Button itself.

Rolerole="group" — declared in the morfo, fixed. A cluster of independent actions. For toolbar semantics (roving focus, single tab stop) use <Toolbar> instead.
LabelProvide aria-label or aria-labelledby — a role="group" without a name is announced as an unnamed group.
Orientationaria-orientation mirrors the orientation prop (horizontal / vertical).
KeyboardEach button stays independently Tab-focusable — no roving. The group itself is not focusable; activation is the native button keyboard (Enter / Space) on each child.
DisabledThe disabled prop propagates to every child Button (each gets aria-disabled) and the group sets data-disabled.
