Sound Radar — accessibility build

```markdown
### 0.12.0 – Fully English UI

* Every user-visible text is now in English: settings screen, buttons, hover
  explanations, command feedback and log lines.
* All strings live in the language files – `en_us.json` is the reference,
  `de_de.json` ships as a complete German translation (German players keep their
  language automatically).
* Nothing user-visible is hard-coded in the source any more, so further
  translations are just another `.json` file.

### 0.11.0 – Crisp HUD, 1:1 preview and developer mode

* **Anti-aliasing is back everywhere:** ring, dots, waves and markers are drawn
  with sub-pixel edge coverage again – no more pixel stairs.
* The settings preview is now **1:1**: it uses the exact ring radius, dot size,
  colours and wave timing of the HUD, so you see changes at their real size.
* **Developer mode:** balancing values (block distance, view cone, line of
  sight, height threshold, quality, background, marker limit) are hidden behind
  a checkbox in the screen (`/soundradar dev on|off` for the commands).
* New **quality switch**: "High" (anti-aliased, default) and "Fast" (~2.6× fewer
  draw commands) for weak setups.

### 0.10.0 – Tick-based animation and smooth motion

* All animations now run on the game clock in **ticks** (20 per second) instead of
  wall-clock milliseconds, so they match the world and stop on pause or
  `/tick freeze`.
* Mob positions are read every **2 ticks (100 ms)** but **interpolated every
  frame** – motion stays smooth at any frame rate while the mod only does
  10 data reads per second.
* The line-of-sight raycast now runs every **5 ticks (250 ms)** and is cached in
  between – 60 % fewer raycasts.
* Blink period 4 ticks (200 ms), waves 20 ticks (1 s), ring pulse 3 ticks
  (150 ms), sound ping lifetime 30 ticks (1.5 s), at most 24 markers.
* All timing values live in one documented file (`Ticks.java`).

### 0.9.0 – Performance fix

* **Fixed massive frame drops.** The HUD used to submit ~6,500 individual draw
  commands per frame (≈390.000 per second at 60 fps). It now renders the same
  picture with ~520 commands – about 12× fewer.
* Rows and rings are merged into single draw commands; small circles are drawn
  row by row without edge blending.
* Mob scanning runs every second tick, and the cheap view-cone check now runs
  before the expensive line-of-sight raycast.
* The dimmed background disc is off by default (it alone cost ~200 commands).
* New: `/soundradar perf` prints the real number of draw commands of the last
  frame, so you can check it yourself.

### 0.8.0 – Accessibility build

* This page now frames the mod for deaf and hard-of-hearing players: the radar is
  a *visual* replacement for the "something is coming closer" sound cue.
* Settings screen with **live preview**, one-line explanations, and
  Save / Reset / Cancel.
* **Mod Menu** integration – the "Configure" button opens the same screen.
* Every option also has a command (see the list further down).

### 0.7.0 – Full command set

* Every setting is available as a client command (`/soundradar`, alias `/sr`).
* In-game settings screen (key `O` or `/soundradar menu`).
* Line of sight is now mandatory for aggro – nothing pulses through walls.
* Anti-aliased rendering: ring and dots stay round at any GUI scale.
* Black outline on every mob dot, smaller default dot size.

### 0.6.0
* Aggro detection rebuilt: follow range + line of sight + view cone
  (`Mob#getTarget` is server-side only and is never sent to the client).

### 0.5.0
* Live mob markers, colour presets, aggro ripples.

### 0.3.0
* Switched from sound pings to live mob positions.
