+  Upstream tokenization: MIT (c) 2026 wanshuiyin -- ../LICENSES/aris-MIT.txt
+  This is the tokenized form of posterly's own neutral template; the class names and
+  content are posterly's own (c) 2026 Ruishuo Chen. As an adapted derivative this file
+  ships as part of posterly under AGPL-3.0. See ../NOTICE.md.
+-->
+<!--
+  ============================================================
+  TEMPLATE: landscape_4col  (ARIS fork)
+  CANVAS:   60in × 36in landscape (ICML / NeurIPS / generic landscape)
+  LAYOUT:   header → optional banner → 4 body columns → optional takeaways → footer
+  USE WHEN: standard ML conference poster with 3-5 content cards per column,
+            mix of figures + equations + small tables.
+  HOW TO USE:
+    1. Copy this file to your working directory as `poster.html`.
+    2. Edit the DESIGN TOKENS in `:root` to your lab/venue colors.
+    3. Replace TODO content placeholders (search for "TODO").
+    4. Run `python tools/run_gates.py poster.html` (the default driver: preflight -> style -> measure -> polish) to align columns and check style/structure.
+    5. Run `python tools/render_preview.py poster.html` to produce the PDF.
+  NOTE: as shipped, this scaffold passes `preflight` (structure) but is
+    EXPECTED to FAIL `measure`/`polish` -- figures are commented out and copy
+    is TODO stubs, so columns only fill the top of the canvas. Those two gates
+    judge a FILLED poster; balance them once you've added real content. See
+    templates/README.md ("Scaffolds, not finished posters").
+  MEASURE ROLES: every layout-critical element carries `data-measure-role`.
+  Generic measurement scripts depend on these — do not remove.
+
+  CANVAS RETARGETING: to print at another size, change the canvas in exactly
+    TWO places that must stay in sync -- the `@page { size: ... }` rule and the
+    `.poster { width/height }` (also the `@media print .poster { width/height }`).
+    Example: ICLR 2026 main conference uses 185cm 90cm landscape (official print
+    service spec) -- set @page to `185cm 90cm`, width to `1850 * var(--u)` and
+    height to `900 * var(--u)` (and the print-override .poster to `185cm`/`90cm`).
+
+  Adapted from posterly (MIT, © 2026 Ruishuo Chen) — see LICENSES/ & NOTICE.md;
