User story

As a user, I want to edit prompts and every generation parameter inline on the Generate screen, so that I can kick off text-to-image jobs without leaving the TUI.

Acceptance criteria

Layout

Generate screen splits per spec §4.1.1: left column with prompt textarea, negative prompt textarea, parameter bar, LoRA list; right column reserved for preview (stub, filled by its own ticket)
Parameters row: Model, Sampler, Steps, CFG, Width, Height, Seed, Batch size, Batch count

Prompt editors

Multi-line textarea supports wrapping, cursor movement (h/j/k/l + arrow keys), word jump (Ctrl+Left/Right), Ctrl+U clear line, Ctrl+W delete word, Ctrl+A select all
Paste event handled via bracketed paste
Syntax highlighting for A1111 attention tokens (word:1.2) and [word] in a distinct colour

Parameter fields

Each field is focusable with Tab; focused field takes edit input
Model / Sampler open a floating combo picker populated from loom-core (PluginBridge)
Steps, CFG, Width, Height, Seed, Batch size, Batch count use number editors; invalid input blocked
Seed: R sets -1, L copies last generated seed (retrieved from loom-core queue history)
Aspect-ratio preset dropdown accessible via Ctrl+Shift+A

Wiring

F5 fires AppAction::GenerateRun(params) which posts to loom-core queue
A validation summary in the status bar blocks submission if required fields are missing
Defaults for all parameters come from AppSettings::generation_defaults

Tests

Unit test: submitting with an empty prompt fails validation
Unit test: entering a model in the combo updates the in-memory params

Out of scope

LoRA panel (separate ticket)
Mode tabs t2i/i2i/inpaint/controlnet (separate ticket)
Real-time preview (separate ticket)
AI prompt enhancement / tag generation (separate ticket)
