P1: DeckPanel + DeckCardRow + DeckStatsBar

[Doberjohn]

The deck list panel + live stats bar with enforcement.

Scope

• DeckPanel (container) + DeckCardRow (thumbnail, quantity stepper, core-card toggle, remove).
• Enforce ≤4 per unique fullName, ≥60 target, ≤2 inks (block adding a 3rd ink; reuse canShareDeck).
• DeckStatsBar: curve mini-chart, ink split, type split, count + legality chip.

Tests/Stories: legal/illegal/over-cap states; data-testids on rows/steppers/count pill.

Part of #451 · Deck Builder & Engine Score milestone.

[Doberjohn]

Partial progress (e52a8be, branch deck-builder): the DeckStatsBar's curve mini-chart + ink split shipped as a cost-curve strip pinned above the Cards-tab deck list (CostCurveStrip.tsx + pure costCurveColumns.ts). Adds a new costCurveByInk field to DeckStats (calculateDeckStats), with dual-ink cards counting toward both inks. Bars are stacked in design-system ink colors, each glowing its dominant ink; render tests + projection tests + a Storybook story + an adversarial review are done.

Remaining for this issue: the DeckStatsBar type split (Characters / Actions / Items / Locations). The count + legality chip already exist as CountBadge / LegalitySummary, and DeckPanel + DeckCardRow already shipped, so the strip completes most of the DeckStatsBar bullet.

This landed as PLAN candidate (a) — the Cards-tab strip, "decoupled from the full advisor." The Analysis-tab variant (candidate b) belongs to #472, not here.
