-- API Key Required screen (shown when no API key):
-- Key icon, title, description, "Open Settings" button
-- Header:
-- Left: conversation title (or "New Chat"), CSS ellipsis on overflow
-- Right: model selector button + dropdown. Groups models by provider.
-- Message area:
-- Welcome screen (no messages, not streaming): robot icon, tips
-- Message list: each has avatar (user=person, assistant=robot), role label, text
-- User messages: plain text
-- Assistant messages: rendered as GFM Markdown
-- External images blocked (CSP), shown as links
-- Tool markers: checkmark/dot, tool name, truncated args (30 char strings)
-- Streaming: accumulating markdown + tool markers, thinking dots animation
-- Auto-scrolls to bottom on new messages
-- Input area:
-- Abort/Stop button (only during streaming, square stop icon)
-- Auto-growing textarea (max 200px). Enter sends, Shift+Enter newline
-- Send button (up-arrow icon), disabled when empty or streaming
-- Token usage tracked per conversation (displayed in status bar, not chat panel).
-- Per-conversation model override via header selector.

value ModelSelectorDropdown {
-- Dropdown in chat panel header for per-conversation model override.
-- Groups models by provider using section headers.
-- Each entry: model display name.
-- Expandable details per model: context window, max output tokens, pricing.
-- Selected model persisted with conversation record.
-- Changing model mid-conversation applies to subsequent messages only.

-- ─── Chat panel actions ─────────────────────────────────────
-- Model selector:
-- Dropdown in header, groups models by provider (optgroup)
-- Selection is per-conversation override, persisted with conversation
-- Changing model mid-conversation applies to subsequent messages only
-- Streaming behaviour:
-- Messages accumulate in real-time (markdown rendered incrementally)
-- Tool call markers: checkmark icon (done) or dot (in-progress),
-- tool name, args truncated to 30 chars for string values
-- Thinking animation (three dots) during LLM processing
-- Stop/Abort:
-- Square stop icon button, visible only during active streaming
-- Stops current generation, partial message preserved as-is
-- Assistant action dispatch:
-- Assistant tool calls can trigger navigation actions:
-- open_post(id), open_media(id), open_settings(), etc.
-- Actions dispatched through store, same as user clicks
-- Navigation actions open tabs with pin intent
