- Implemented a new crate `hcie-watercolor-brushes` containing watercolor brush presets and a procedural splat preview renderer. - Integrated watercolor brushes into the iced GUI's Brushes panel, adding a new category for watercolor brushes. - Updated the `BrushCategory` enum to include `Watercolor` and modified the rendering logic to display watercolor presets. - Added functionality to generate watercolor splat thumbnails using a noise-based algorithm. - Ensured that existing brush styles and engine crates remain unmodified, adhering to project constraints.

Comprehensive Drawing & Painting Media Reference Guide
A Structured Classification System for Traditional Tools and Digital Brush Architecture
1. Dry & Graphic Media
Graphite & Charcoal
- Graphite Pencils: Graded by hardness and darkness from 9H (hardest) to 9B (softest).
- Carpenter Pencil: Broad, flat-graphite core for wide strokes and varied line weights.
- Powdered Graphite: Fine graphite dust used for large-area shading and smooth tonal blending.
- Compressed Charcoal: Dense charcoal bound with gum, producing deep, rich blacks and hard lines.
- Willow / Vine Charcoal: Burnt natural twigs; soft, powdery, and easy to erase or smudge.
- Charcoal Pencil: Encased in wood for clean handling and precise detail work.
Pastels & Chalks
- Soft Pastels: High pigment content with minimal binder; offers powdery, easily blended colors.
- Hard Pastels (Conté Crayon): Higher binder content; ideal for sharp edges, outlines, and details.
- Oil Pastels: Bound with non-drying oil and wax; buttery texture with strong opacity.
- Water-Soluble Pastels: Can be used dry or dissolved with water to create watercolor-like washes.
- PanPastel: Cake-format pastel applied using specialized sponges and applicators.
- White Chalk & Sanguine: Traditional earthy monochrome media used for highlights and anatomical studies.
Colored Pencils
- Wax-Based Colored Pencils: Soft core, ideal for rich color layering and blending.
- Oil-Based Colored Pencils: Harder core, break-resistant, well-suited for fine detail work.
- Watercolor Pencils: Water-soluble pigment cores that react with wet brushes.
2. Inks & Markers
Markers & Felt-Tip Pens
- Alcohol-Based Markers: Fast-drying, streak-free blending ink (e.g., Copic).
- Water-Based Markers: Water-soluble ink; ideal for general illustration and light wash effects.
- Acrylic Paint Markers: Opaque, water-based acrylic paint for multi-surface application (e.g., Posca).
- Brush Pens: Flexible nibs (felt or synthetic hair) for variable stroke width in ink illustration.
Inking Instruments
- Indian / Drawing Ink: Waterproof, highly opaque shellac- or acrylic-based liquid ink.
- Dip Pen / Nib Pen: Traditional metal nibs dipped into ink for calligraphic or cross-hatching work.
- Technical Pens (Rapido): Precision engineering pens delivering exact, consistent line widths.
- Fineliners / Graphic Liners: Pigment-based, lightfast, fine plastic-nibbed pens for line art.
3. Wet & Painting Media
Watercolors & Water-Based Paints
- Tube & Pan Watercolors: Highly transparent pigments activated by water for delicate layering.
- Liquid Watercolors: Concentrated fluid pigments popular in graphic arts and illustration.
- Gouache: Opaque watercolor drying to a smooth, matte finish.
- Acryla Gouache: Water-based paint combining gouache opacity with acrylic water-resistance when dry.
Oils & Acrylics
- Traditional Oil Paint: Linseed oil binder; slow-drying, allowing extensive blending and impasto.
- Water-Mixable Oil Paint: Modified oils that thin and clean up with water without solvents.
- Heavy Body Acrylic: Thick, buttery consistency that retains brush and palette knife marks.
- Fluid & High-Flow Acrylic: Low-viscosity acrylics for smooth coverage, glazing, or airbrushing.
- Egg Tempera: Fast-drying traditional medium using egg yolk as a binder.
4. Digital-Specific Brush Classifications
Digital Engine Types
- Pixel / Raster Brushes: Simulates traditional media textures using bitmapped stamps and opacity dynamics.
- Vector Brushes: Creates resolution-independent paths with editable stroke profiles.
- Smudge & Blending Tools: Manipulates existing canvas color without applying new pigment.
- Stamp & Texture Brushes: Applies pre-rendered patterns or shapes (e.g., foliage, skin texture, clouds).
- FX & Dynamic Brushes: Particle- or physics-based brushes generating glows, sparks, or fluid effects.
