Subject: [PATCH] feat(treasury): explain the lumpy fee accrual on the
 sponsorship card
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Morpho VaultV2 mints the fee on vault interactions, not continuously —
Yan's figure once jumped 66x in a day when a partial withdrawal realised
about a month of accrual at once, and without the mechanism stated on
the card that reads as a bug. Two sentences, both locales: fees
materialize on interaction, can sit still for weeks then jump, and an
older small vault can carry more accrued fee than a big recent one.
