Port status

Every upstream piece, at the commit in UPSTREAM.md. Generated by mix run tools/port_status.exs; notes come from tools/port_notes.exs.

191 pieces. green: 191, tolerance: 0, blocked: 0, todo: 0.

• green: registered, and frame-for-frame identical to upstream in every golden run, text and colours (test/pieces/<slug>_test.exs).
• tolerance: identical except for the cells allowed in test/fixtures/tolerances.exs (see PORTING.md).
• blocked: cannot be matched; not registered; the note says why.
• todo: not ported yet.

Frame times are milliseconds on average, played as upstream's scripts/check.ts times them (every 1/fps seconds for 6 s), on the machine that generated this file. Upstream's budgets: text pieces 4 ms, scenes 10 ms; a piece over its budget says so.
