+Noctalia theme change request (yellow to red, terminal text same red) led to locating Noctalia/Niri config surfaces and crispness controls. No final edit was applied before abort. Durable: Noctalia is Niri-based; palette generated via noctalia theme image; Ghostty uses theme=noctalia; niri compositor AA only affects corner rounding, while blur/noise cause soft glass look and text AA is client-side.

+Rotated two external PNP(XYM) PM1601 portable monitors 180° in portrait via niri display config edit. Key insight: in portrait mode, a 180° flip is the 90°↔270° transform swap, not adding 180°. Workflow: niri msg outputs → edit cfg/display.kdl → niri validate → niri msg action load-config-file → verify → git commit/push.

+llama.cpp parallelism types: two real model-parallelism modes (pipeline/layer split = default, tensor = experimental), plus deprecated 'row' and single-GPU 'none'. --parallel is a separate serving-level concurrency axis, not model splitting. No first-class context/sequence parallelism. Tensor mode requires flash attention, non-quantized KV, and excludes MoE/Mamba/SSM architectures.

+Re-arranged blankpad niri display: moved two rotated PM1601 externals (DP-2, HDMI-A-1) from right of eDP-1 to left. New x-chain: DP-2@0 → HDMI-A-1@1200 → eDP-1@2400. Committed as 83c9c92 to dank/command-center.
