# Sprint 33: Pecunia — Client Tasks

**Goal:** Full economics simulation running — Leontief production, spatial price equilibrium, currency zones, corporate behavioral agents across all three corporation tiers, stability tests passing.

**Branch:** `sprint-33/client`
**Agents:** Stig (UI dev)

## Key Decisions

- `decisions/architecture.md` — D-169 (implant UI component library), D-170 (HUD visibility groups)

## Notes

**#818 — Create icon_tint.gdshader for runtime icon recoloring**
- The implant HUD icon set (D-086, #795) references `icon_tint.gdshader` for runtime color replacement via ShaderMaterial. This shader was assumed to exist but was not authored during Sprint 32.
- The shader must handle two icon types:
  - **Stroke-based icons** (majority of the set) — the icon is drawn as colored outlines/strokes on a transparent background. Recolor by replacing the stroke color at runtime.
  - **Fill-based icons** (health cross, at minimum) — the icon is a solid filled shape. Recolor the fill.
- Integration spec: `docs/design/icon-set-v01.md` section 3.2 details the Godot ShaderMaterial parameter interface. Read that section before writing the shader.
- Placement: `client/ui/implant/` or `client/shaders/` — check where other shaders live in the client tree and follow the existing convention.
- The shader takes a `ShaderMaterial` parameter (the tint color) and outputs a recolored version of the source texture, preserving alpha. The icon textures are single-color SVG exports — the shader replaces the source color, not a specific channel.
- Test by attaching to an `ImplantDataRow` or standalone `TextureRect` with one of the HUD icon textures. Verify both stroke and fill icon types recolor correctly at all implant theme semantic colors (`ACCENT_ACTIVE`, `ACCENT_POSITIVE`, `ACCENT_NEGATIVE`, `ACCENT_WARNING`, per `client/ui/implant/default_implant.tres`).
- This is a standalone task — no server-side dependencies.
