Land SPEC-085's sizing model and the placement/link affordances. One grid, one vocabulary: a 6-column default, proportional size presets, and precise cols/rows.
Tracking started Jun 5 — check back for trends.
columns defaults to 6 for both authoring modes (author-overridable); the mode-dependent tiered=4 / span=6 split and the sizing="span" parent mode are removed.size presets resolve as proportions of the column count (small ⅓, medium ½, large ⅔ × 2 rows, full = all → 2/3/4/6 @ 6 cols), so they hold their ratio at any columns.cols / rows map to grid-column: span / grid-row: span and override size per-axis when present.grid-auto-rows: var(--rf-bento-row-height) (a fixed, themeable height — not tied to column width, which would explode vertically on collapse). Row spans (rows / large) are therefore meaningful, and a tall guest is bounded by the track (it scales/clips via WORK-339) rather than ballooning the whole row. Row height may vary per breakpoint but is never coupled to the column width.{% bento collapse="sm|md|lg|never" %} sets the breakpoint at which the grid drops to a single stacked column (with a sensible default), replacing the hard-coded !important final collapse.min(span, current-columns) — no per-size !important overrides — so wide cells degrade gracefully at each step. (Per-cell responsive spans are deferred — WORK-354.)media-position is author-controllable per cell (top | bottom | start | end) with a size-derived default (small → media top/stacked; large/full → prominent / beside).href makes a whole cell a link (mirrors card), with correct focus/hover affordances and accessible markup.data-media-position + the resolved spans, reusing the shared split.css / card media rules where possible.size preset proportion, cols/rows overrides, the tiered depth→size mapping, each media-position value, and a link tile. Existing heading-sugar bentos keep their proportions (verify).Resolve size/cols/rows to grid spans in the cell transform/CSS (custom properties keyed off the cell size/span data). Lean on split.css / card media rules for placement so bento and card share behavior. Verify the canonical bento.md and any other usages still read well at the new 6-col default.

columns ?? 6); the old mode-dependent split + sizing="span" are gone (removed in WORK-345).presetSpans(size, columns) resolves a preset to (cols, rows) as a fraction of the column count (small ⅓, medium ½, large ⅔×2, full = all → 2/3/4/6 @ 6 cols), so a preset holds its ratio at any columns. convertHeadings computes them per cell.cols / rows are first-class cell attrs → --cell-cols / --cell-rows → grid-column/row: span; they override the preset per axis.grid-auto-rows: var(--rf-bento-row-height, 12rem), never column-tied, so spans are meaningful and tall guests are bounded (WORK-339) instead of ballooning.{% bento collapse="sm|md|lg|never" %} → data-collapse; CSS drops the grid to one column at that breakpoint (replacing the !important final collapse), with automatic progressive reduction in between (--bento-cols-effective steps 6→4→3→2→1; every span auto-caps via min(--cell-cols, --bento-cols-effective)).data-media-position (top|bottom|start|end) via a flex layout, with a size-derived default (large/full → start/beside, smaller → top).bento.css accordingly; 10 bento tests; regenerated both contracts; size made noBemClass (spans come from cols/rows, not a size class).cols/rows-override and href-link-tile tests require explicit {% bento-cell %} authoring, which lands in WORK-347 — the transform mechanism (attrs → spans → grid, href) is in place and exercised by the sugar path's computed spans.
