Studio: the first real flash buttons — teiOS UF2s hosted with a manifest.

web/public/teios/: teios-feather-rp2040.uf2, teios-pico.uf2,
teios-pico2.uf2 (built from the E1a/E1 firmware) + manifest.json — the
forge's catalog shape v0: per-image board_id, uf2_family, sha256,
bytes, install tier, drive name, protocol id, substrates, and honest
joules provenance ("table — ILLUSTRATIVE pending bench calibration").

/studio board cards for the Feather RP2040 and Pico-class gain working
FLASH teiOS download buttons with the three-step W2 instructions (hold
BOOTSEL, drag onto RPI-RP2, CONNECT above). Minutes-to-first-ledger is
now fully real for any RP2040 board, no install, no account: download,
drag, connect, watch your board dispatch. Verified headless: manifest
served hash-consistent, 3 buttons rendered, download works, zero JS
errors. Pico 2 image marked hardware-unverified (none on the bench).
