Close the Phase 1b debt: the "## Handoff 2026-05-14" blocks embedded at
the top of arts/README, arts/adom/README and arts/format/README move to
docs/process/handoffs-2026-05.md, so the layer references read as
timeless. Same mechanical pattern already applied to the UIX READMEs in
41c3b0f9.

Toggle as the eidos pilot: subdirectory layout (recipe + Svelte wrapper +
types + index + README) replacing the flat CSS-only form. Pattern is
documented in eidos/components/README.md and the toggle README.
Shared types live in eidos/lib/types.ts. First export is `Size` (8 values
xxs..xxl + full); components narrow with `Extract<Size, ...>` per the
per-component-subset doctrine. No `Eidos` prefix on types — module path
already conveys the layer.
API doctrine:
- soma stays compound (Toggle.Provider) for symmetry with multi-part
- eidos exports both default + Provider so single-part components
accept both `<Toggle>` (ergonomic) and `<Toggle.Provider>`
(compound-style consumers)
SoundChannel eager-init fixes the autoplay race: AudioContext is created
+ resumed synchronously on the first user gesture (capture-phase
listener registered in the constructor), avoiding the previous race
where the first emit() scheduled the resume in a microtask outside the
gesture window.
Demo page (web/routes/toggle/+page.svelte) restructured so the live
preview renders ALWAYS above the tablist — Sema-tab Play buttons can
fire on the real toggle. Motion preview amplifies scale ×8 visually
only; doctrinal values stay in the <dl>.
Conventions 7-13 added to src/docs/sema-implementation-guide.md
covering: directory structure, wrapper composition, no Eidos prefix,
soma compound vs eidos flat, iconOnly sr-only body, sound eager-init,
docs-preview amplification.
CLAUDE.md gets a session hand-off block listing where things stand and
next concrete steps (migrate switch/collapsible/dialog/drawer/popover/
toast/avatar; wire topbar sound mute to masterGain; rename theme
tokens to drop the success/warning/danger fallback aliases).
