	============================================================
	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;
	ARIS modifications: flat de-gradient, --fs token scale, zero-inline-style
	utilities, data-source/data-color-exempt contracts.
