Measured Borrowings

0.43 g — shell fragment weighed against an estuary afternoon; tide calibration ±0.01 g.

3.2 cm — anemone foot clasp span, indexed to borrowed oyster architecture.

Salinity: 27.8 PSU — sensor reads the mouth; sediment hums in thirds.

(the ledger admits a small theft, soft as a held breath)

0.6 mm — barnacle scaffold overlap; record the polite usurpation.
