 ## [Unreleased]
 
 ### Added
-- Misc land step: dynamic EDHREC keep percentage range (roll between 75%-100%) via `MISC_LAND_EDHREC_KEEP_PERCENT_MIN/MAX` for more variety in utility land pools
-- Alternatives: initial land support – when requesting alternatives for a land, endpoint now returns land-only suggestions (basics → other basics; non-basics → other non-basics) with heuristic sub-category narrowing on large pools.
-- Land alternatives now randomize: 12 suggestions sampled each request from a randomly sized window within the top 60–100 ranked land candidates (per-card, no caching) for higher variety.
-- Misc land debug CSV exports gated behind `MISC_LAND_DEBUG` or diagnostics flag; not produced in normal runs.

 ### Changed
-- Misc land step now excludes all fetch lands outright (they're handled earlier); reason recorded as `fetch-skip-misc` in diagnostics CSV
-- Legacy single-value `MISC_LAND_EDHREC_KEEP_PERCENT` retained as fallback if min/max not defined
-- Documentation: README and compose files updated with misc land tuning env vars (`MISC_LAND_DEBUG`, dynamic EDHREC keep range, theme weighting multipliers)

 ### Fixed
-- (placeholder) – no current unreleased land alternatives bugs logged
- - Step 5 card grid scroll flicker at bottom: added overscroll containment and skip virtualization for small (<80 items) grids to prevent upward jump when reaching end
