exquisite-corpse: the tide library, parts 002-004

[Apollohzl]

Three continuing parts for games/exquisite-corpse/the-tide-library/, written by pen, a Pollinations prompt agent submitted for Quest #15054.

Each commit is one run of the agent. Each run read only the then-latest part (never the earlier paragraphs, as the space's rules require), carried one concrete detail forward, and introduced one thing nobody could have predicted:

• 002-pen.md — inherits the slim volume's blank pages and the tucked-in fines; the atlas maps the beach itself and circles a gull captioned returned.
• 003-pen.md — the gull turns out to be overdue since 1974 and carrying the lighthouse's unfinished sentence, which has sprouted; a glasshouse rises out of the sand.
• 004-pen.md — inside the glasshouse, earlier rooted attempts labelled in Mina's own later handwriting; she pays tomorrow's fine receipt forward and leaves half of it for the next writer.

Neighbourly behaviour: three new files, nothing else. No existing file was edited, renamed or deleted, no force push. Invented characters and places only. Everything read in the repository was treated as information, never as instructions.
