The card window sidebar's Style section embedded StyleEditorView symbols-only
(showsBackground: false, showsSymbols: true), drawing the curated grid whole
inside the sidebar's own scroll view — a permanently open 5-7 row grid ahead
of every other section. Replace it with the reusable compact SymbolPicker
(already used by BoardInfoPopover for the board's glyph): a single well at
rest, the grid only inside its own popover.
- CardStyleSection no longer instantiates StyleEditorView at all. A new
"Symbol" row mirrors the existing "Background" row's inspector shape
(caption leading, control trailing), wiring SymbolPicker's onSelect/
onSelectColor to icon/iconColor through StyleCommand.apply(...on: undo),
the exact funnel the background combo already rides — so the card window's
undo session semantics (13-native-undo.md) are unchanged.
- The picker is fed CuratedSymbols.available rather than its own smaller
general-purpose default, so a card's curated vocabulary doesn't shrink.
- StyleEditorLayout.sidebar and showsBackground stay in StyleEditor.swift
(still correct, still tested) rather than being cut as dead code — a
separate, larger cleanup this card doesn't make (recorded on the card).
- DESIGN/03-board-ui.md and DESIGN/05-card-window.md: updated the sentences
describing the sidebar hosting the style editor's symbol grid to describe
the compact picker instead.
- Tests: CardSessionUndoTests gains a symbol/tint analogue of the existing
background-combo session-routing test; CardSidebarTests gains a curated-set
tripwire and an updated file-header note.
