+- [x] **4.4l — Confirm actual booted framebuffer resolution, all three architectures.**
   Investigation only. amd64 already confirmed this session: 1280×800 (QEMU/OVMF GOP default,
   read directly off the 2026-08-11 verification screendump). aarch64/riscv64 unconfirmed.
   *Done when:* resolutions for all three architectures are recorded here from real
   screendumps or boot logs, not assumed.
   *Refs:* §27.8.

 - [ ] **4.4m — Decide REPL-strip pixel height.** Currently undefined anywhere in this document
   or the code. Once 4.4j lands, REPL text renders via `TTF-TEXT` at some chosen point/pixel
   size (also not yet chosen) — strip height derives from that size's line height plus padding,
