dsh-appearance-english

A unified appearance coordinator: merges dsh-theme (palettes / font families / interface sizes) and dsh-custom-workspace (per-workspace body font size / line height / paragraph spacing / background) into a single plugin row, and defines a single source of truth for body font size, eliminating the mutual-override problem.

Coordination rules (why they no longer conflict)

Chat body text consumes exactly one CSS variable: .markdown { font: var(--dsw-font-markdown-base) }.

• The only source of body font size (--dsw-font-markdown-*) = the workspace settings. Workspaces without an explicit setting inherit the DSH official default (16px / 28px).
• The dsh-theme half no longer emits markdown-family overrides; its "interface size" only scales interface elements (sidebar, buttons, headings, and other UI tokens) without also enlarging the body text.
• The coordinator listens to theme/change: every time the official theme presenter rewrites the body tokens, the coordinator re-applies the current workspace's appearance (workspace wins; unset fields fall back to the global theme).

Settings entry points

• Settings → Appearance: palettes (9 presets + custom), interface font, code font, interface size, code size (interface only — never body text).
• Settings → General settings → Workspace appearance: per-workspace background color/image, body font size, line height, paragraph spacing, Retina rendering.

Persistence

• Theme settings are stored in browser local storage (same as dsh-theme, key dsh-theme/settings/v1).
• Workspace appearance is stored in the dsh-appearance-english namespace of $DSH_HOME/settings.yaml (host settings + loopback RPC).

Model footprint

None. It only affects browser rendering; it never enters model requests.
