Sidebar: Spaces tree with lazy-expand to projects on caret click; bottom
Navigate section with Sacred Valley / Search / Inbox + placeholders for
Agents and Resources greyed out as later. Inbox item carries a
pending-count badge that wires to state.js so the topbar bell and the
sidebar share one poll.
Topbar: brand, + Capture button (modal stub for Plan 3 capture queue),
global search input (Enter -> /search?q=), pending Inbox bell with
matching badge, Owner toggle (stub for agent-switching post-Plan-2).
Rightrail remains the T17 collapsible companion placeholder.

Three-column grid (sidebar / main / right rail) with Cradle aesthetic:
blackflame accent on Cinzel display headings + Cormorant Garamond body
in cards, system UI for chrome. Hash-based router covers all entity
routes plus search, inbox, sacred-valley. api.js stores OWNER_TOKEN in
localStorage and prompts via a modal on 401. dom.js provides safe el()
+ mount() builders so no component ever assigns innerHTML from API data
(the only exception is an explicit, scary-named html: opt-in for
sanitizer output, used later by the markdown editor).
state.js is a tiny event bus for shared chrome state (pending count).
Components and views are loaded as ES modules — sidebar / topbar /
rightrail + 9 view stubs that the later Phase E tasks fill in.
