| ============================================================ | |
| TEMPLATE: portrait_2col (ARIS fork of posterly portrait_2col_neutral) | |
| 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. | |
| CANVAS: 24in × 36in PORTRAIT (ICLR / CVPR / many workshops default) DEFAULT. | |
| CANVAS RETARGETING: change BOTH the @page `size` (one place, in the | |
| CANVAS block below) AND the .poster `width`/`height` (one place, in | |
| the .poster rule). Keep them in sync. | |
| NOTE — ICLR workshops commonly mandate a 61×91 cm PORTRAIT board | |
| (A0-ish portrait). To retarget to that: | |
| @page { size: 610mm 910mm; } /* or 61cm 91cm */ | |
| .poster { width: calc(610 * var(--u)); height: calc(910 * var(--u)); } | |
| (1 print --u = 1mm, so 610/910 u == 610/910 mm == 61×91 cm — almost | |
| identical to the shipped 24×36in default, which is why portrait is a | |
| good fit for ICLR-workshop boards.) | |
| LAYOUT: header → body 2 columns → footer | |
| (NO framework banner, NO takeaways strip — vertical space is precious) | |
| USE WHEN: venue mandates portrait orientation, sub-A0/A1 size; | |
| reader scans top-to-bottom in column 1, then jumps to column 2. | |
| HOW TO USE: | |
| 1. Copy this file to your working directory as `poster.html`. | |
| 2. Edit the DESIGN TOKENS in `:root` (or swap a tokens/*.json palette) — | |
| the token block is the ONLY place color/font-size literals may live. | |
| 3. Replace all placeholder content with audited reproduction evidence. | |
| 4. Run `python3 tools/run_gates.py poster.html` (the default driver: preflight -> style -> measure -> polish) to align columns and check style/structure. | |
| 5. Run `python3 tools/render_preview.py poster.html` to produce the PDF. | |
| STYLE CONTRACT (ARIS source gate, tools/style_check.py): | |
| - NO inline `style=` attributes anywhere in the markup. Use the utility | |
| classes (.fs-N, .mt-N, .mb-N, .w-NN, .text-secondary, .nowrap, | |
| .text-center) defined in the UTILITIES block below. | |
| Sole exceptions: the internal SVG of a `data-color-exempt="logo"` element, | |
| and a `style="width: NN%"` on a `data-source="paper"` <img> (AR width tweak). | |
| - All font-size values reference a `--fs-1..9` token (or a COMPONENTS.md | |
| predefined `calc(var(--fs-N) * k)` variant such as `.eqn--large`). | |
| - No `linear-gradient`; the only gradient allowed is the .poster radial | |
| tint (every color stop alpha ≤ 0.06). | |
| MEASURE ROLES: every layout-critical element carries `data-measure-role`. | |
| Generic measurement scripts depend on these — do not remove. | |
