feat: three-tier performance presets (Low/Medium/High) for client + server

Add drop-in performance presets tuned for three hardware tiers. Tier targets: - Low: 4GB VRAM/iGPU, 8-16GB RAM - Medium: RX 580-class 8GB, 16-32GB RAM (shipped as pack default) - High: RTX 3060+ 8GB+, 32GB+ RAM Client configs (per tier, presets/<tier>/config/): - sodium-options.json: chunk threads, cpu render-ahead, quality - iris.properties: shaders on/off, max shadow render distance - lambdynlights.toml: dynamic lighting mode + adaptive ticking - entityculling.json: culling tracing distance - cullleaves.json: leaf culling - soundphysics.properties: reverb/ray budget (CPU cost) - flywheel-client.toml: Create backend (BATCHING vs INSTANCING) Server configs (per tier, presets/<tier>/server/): - server.properties: view-distance, sim-distance, players, compression - jvm-flags.txt: heap + G1 GC flags per RAM tier Medium configs also copied to client_pack/config/ so they ship as the mrpack defaults (bundled into overrides/config/). Docs: docs/performance.md + docs/server.md rewritten for three tiers; presets/README.md explains how to apply each tier. Default (Medium) enables shaders with INSTANCING flywheel on the 8GB GPU tier; Low disables shaders + uses BATCHING for maximum FPS on weak GPUs.

 # Performance — Client

-## Shader Tuning for 4GB VRAM
+Three drop-in tiers are provided: **Low**, **Medium**, and **High**. The
+**Medium** tier ships as the pack default (matches a Ryzen 5 5600X / 16-32 GB
+RAM / RX 580 8 GB machine). Full details and copy commands live in
+`presets/README.md`.
+
+| Tier | Target | Shaders | Render distance | Key trade-offs |
+|------|--------|---------|-----------------|----------------|
+| **Low** | 4 GB VRAM / iGPU | **Off** | 4-6 | Minimal effects, most CPU headroom |
+| **Medium** | 8 GB VRAM (RX 580-class) | On (Complementary, Performance) | 8 | Balanced 60 FPS — **default** |
+| **High** | 8 GB+ VRAM (RTX 3060+) | On (Complementary, Ultra) | 10-12 | Max visual quality |
+
+## Applying a tier
+
+```bash
+# client configs → instance config dir
+cp -r presets/low/config/* ~/.local/share/PrismLauncher/instances/<instance>/minecraft/config/
+```
+
+Restart the game after copying. See `presets/README.md` for the full file map.
+
+## What each tier changes
+
+| Config | Low | Medium | High |
+|--------|-----|--------|------|
+| Sodium chunk threads | 1 | auto | auto |
+| Sodium cpu render-ahead | 1 | 3 | 4 |
+| Sodium quality | FAST | DEFAULT | DEFAULT |
+| Iris shaders | **off** | on, shadow 32 | on, shadow 64 |
+| Dynamic lights | simple | fancy | fancy (max) |
+| Entity culling distance | 64 | 128 | 192 |
+| Sound reverb rays | 16 | 24 | 32 |
+| Flywheel backend | BATCHING | INSTANCING | INSTANCING |
+
+## Shader tuning (Complementary Reimagined r5.4)

 Shader loader is **Iris** (native NeoForge). Recommended shaderpack:
 **Complementary Reimagined r5.4** (`client_pack/shaderpacks/`, see README).

-Preset for 4GB VRAM:
- Preset: **Fast / Performance**
- Render Distance: **8** (server view-distance)
- Antialiasing: **OFF**
- SSAO: **Fast**, Shadow Quality **1.0x** (0.5x if <30 FPS)
- Shadow Distance: **64**
- Bloom: **OFF/Low**, Clouds: **2D Fast**
- Water Reflections: **Screenspace Fast**
- Colored Light / Block Light: **OFF**
+In-game (`Esc → Options → Shader Packs → Complementary → Shader Pack Settings`):

-If still under 60 FPS: reduce Shadow Quality to 0.5x, then disable Bloom,
-before touching render distance.
+### Medium (8 GB VRAM)
+- Preset: **Fast / Performance**
+- Antialiasing: OFF, SSAO: Fast, Shadow Quality 1.0x
+- Shadow Distance: 64, Bloom: Low, Clouds: 2D Fast
+- Water Reflections: Screenspace Fast, Colored Light: OFF
+
+### High (8 GB+ VRAM)
+- Preset: **High / Default**
+- Antialiasing: OFF or FXAA, SSAO: High, Shadow Quality 1.5x
+- Shadow Distance: 128, Bloom: On, Clouds: 3D
+- Water Reflections: Screenspace, Colored Light: On
+
+### Low (no shaders, or "Potato")
+- Play with shaders **off** (Iris `enableShaders=false`).
+- If you want them on, use Complementary "Potato/Ultra" preset, shadows OFF.
+
+If FPS is still low, lower Shadow Quality / disable Bloom before touching
+render distance.

 ## Reload rules

 - Server scripts / recipes / advancements: `/reload`
 - Client tooltips / JEI / textures / lang: `F3+T`
- New items/blocks (`registry_blocks.js`): **full restart**
+- New items/blocks (`registry_blocks.js`): **full restart**
+- Config files (Sodium, Iris, etc.): **full restart**

+# Performance Presets — SCICRAFT
+
+Three drop-in tiers for client (and server) tuning. The **Medium** tier is the
+pack default — it ships inside the mrpack (`overrides/config/`) and matches a
+Ryzen 5 5600X / 16-32 GB RAM / RX 580 8 GB class machine.
+
+To use a different tier, copy the files from the matching folder into the
+`.minecraft/config/` directory (client) and the pack's `server/` directory
+(server), then restart.
+
+## Tier targets
+
+| Tier | CPU | RAM | GPU | Use case |
+|------|-----|-----|-----|----------|
+| **Low** | 4-core / older | 8-16 GB | 4 GB VRAM or iGPU | Integrated graphics, laptops, weak desktops |
+| **Medium** | 6-8 core (5600X-class) | 16-32 GB | 8 GB VRAM (RX 580-class) | **Default. Balanced 60 FPS.** |
+| **High** | 8+ core | 32 GB+ | 8 GB+ VRAM (RTX 3060+) | High FPS at high render distance / shaders |
+
+## What's included per tier
+
+### Client (`presets/<tier>/config/` → `.minecraft/config/`)
+
+| File | Effect |
+|------|--------|
+| `sodium-options.json` | Terrain renderer: chunk threads, culling, quality |
+| `iris.properties` | Shader loader: on/off, max shadow render distance |
+| `lambdynlights.toml` | Dynamic lighting quality / adaptive ticking |
+| `entityculling.json` | Entity/block-entity culling distance |
+| `cullleaves.json` | Leaf culling on/off |
+| `soundphysics.properties` | Reverb/ray budget (audio CPU cost) |
+| `flywheel-client.toml` | Create/Flywheel render backend (batching vs instancing) |
+
+> Note: `sodium-mixins.properties` is left at default on all tiers. Hand-editing
+> Sodium mixin flags can cause crashes, so we tune the safe, supported options
+> (`sodium-options.json`) instead.
+
+### Server (`presets/<tier>/server/`)
+
+| File | Effect |
+|------|--------|
+| `server.properties` | view-distance, simulation-distance, compression |
+| `jvm-flags.txt` | Recommended JVM heap + GC flags for that RAM tier |
+
+## Applying a tier (client)
+
+```bash
+# Example: switch to LOW
+cp -r presets/low/config/* ~/.local/share/PrismLauncher/instances/<instance>/minecraft/config/
+```
+
+Then restart the game. Shader-pack in-game settings (Complementary) still
+override a few visual options — see `docs/performance.md`.
+
+## Applying a tier (server)
+
+```bash
+# Example: switch to LOW
+cp presets/low/server/server.properties server_pack/server.properties
+# use the jvm-flags.txt line when launching
+```
+
+## Notes
+
+- **Shaders are disabled on the Low tier** — this is the single biggest FPS win.
+  On Low, either play without a shaderpack or use an "Ultra/Performance"
+  preset of Complementary with shadows off.
+- **Medium is the shipped default** — the mrpack already contains these configs,
+  so players who do nothing get the balanced experience.
+- `enableShaderCompatibleRendering` is on for Mekanism Covers on all tiers so
+  covers render correctly with shaders.
