 - Fixed llama.cpp discovery to prefer per-model `/v1/models` `meta.n_ctx`/`meta.n_ctx_train` values, refresh selected models after lazy load, and bypass fresh-cache reuse so server restarts update context windows. ([#3310](https://github.com/can1357/oh-my-pi/issues/3310))
 - Fixed `task.maxConcurrency: 0` serializing subagent spawns instead of running them unbounded. The settings UI labels `0` as "Unlimited", but the session-scoped spawn `Semaphore` clamped `max` via `Math.max(1, max)`, so the second subagent body in a batch always waited for the first to release the seat. The constructor now treats `max <= 0` (and any non-finite input) as unbounded via `Number.POSITIVE_INFINITY`, matching the eval `parallel()`/`pipeline()` worker-pool semantics ([#3305](https://github.com/can1357/oh-my-pi/issues/3305)).
 - Fixed MCP tool calls forwarding empty optional placeholder arguments (`""` and `{}`) to `tools/call`; optional placeholders are now omitted while required fields and meaningful falsy values are preserved. ([#3302](https://github.com/can1357/oh-my-pi/issues/3302))
+- Fixed the welcome `Tip:` line rendering with hardcoded `#b48cff` / `#9ccfff` pastels plus a manual `\x1b[2m` dim, so any light theme dropped the body to ~1.5:1 contrast (well under WCAG AA). `renderWelcomeTip` in `packages/coding-agent/src/modes/components/welcome.ts` now paints the label through `theme.fg("customMessageLabel", …)` and the body through `theme.fg("muted", …)` (no manual dim), so the line tracks the active theme and stays legible on light backgrounds. ([#3337](https://github.com/can1357/oh-my-pi/issues/3337))
