+
+## Partner and funding logos
+
+Enable partners in the preamble, in the desired display order:
+
+```latex
+\partner{labsticc}\partner{ubo}\partner{aid}\partner{ifremer}
+```
+
+Logos for the following partners are included in `img/partners/`:
+
+| Identifier | Partner |
+| --- | --- |
+| `labsticc` | Lab-STICC |
+| `ubo` | Université de Bretagne Occidentale |
+| `ensta` | ENSTA, Institut Polytechnique de Paris |
+| `aid` | Agence de l'innovation de défense |
+| `ifremer` | Ifremer |
+| `lip6` | Laboratoire d'informatique de Sorbonne Université |
+| `sorbonne` | Sorbonne Université |
+| `academia-sinica` | Academia Sinica |
+| `taipei` | University of Taipei |
+
+For example, enable the additional four with:
+
+```latex
+\partner{lip6}\partner{sorbonne}\partner{academia-sinica}\partner{taipei}
+```
+
+Enable ENSTA with `\partner{ensta}`.
+
+Asset sources are recorded in [`img/partners/README.md`](img/partners/README.md).
+Add other individual logos in `img/partners/`, named after their identifier:
+
+```text
+img/partners/labsticc.png
+img/partners/ubo.png
+img/partners/aid.png
+img/partners/ifremer.png
+```
+
+PNG, PDF, JPG and JPEG are supported, searched in that order. All nine bundled
+assets are transparent PNGs. Prefer high-resolution transparent PNGs or vector
+PDFs, tightly cropped to the artwork;
+embedded white space counts towards a logo's dimensions. SVGs should first be
+exported to PDF. The existing `img/logos.png` is a combined UBO/Lab-STICC image,
+not two independently selectable logos.
+
+For other file locations or identifiers, register a path (with or without its
+extension) and then enable the partner:
+
+```latex
+\declarepartner{my-funder}{img/custom-funder.pdf}
+\partner{my-funder}
+```
+
+The title page places the logos at the bottom right, inside the theme's margins.
+Column count, logo sizes, cell sizes, spacing and row wrapping are computed from
+the number of available logos, their aspect ratios, the column width and the
+slide height. Logos have equal bounding-box area for comparable visual weight:
+wide wordmarks are shorter than square seals, rather than dominating the block.
+Aspect ratios are preserved; logos are centred within evenly spaced grid cells.
+The final row is right-aligned and stays within a bounded title-page area.
+Repeated selections are ignored. Missing files produce warnings and are skipped,
+without inserting placeholder logos. Partners do not appear on ordinary slides.
+
+With no partners selected, the existing `\titlegraphic{...}` is still used.
+When partners are selected, they replace the legacy title graphic.
+
+### Additional information
+
+No additional logo files are needed for the nine included partners. If a funder
+requires a specific logo variant, minimum size, ordering or acknowledgement text,
+provide those project-specific requirements. No manual layout dimensions are needed.

+| `ensta.png` | Official blue vertical ENSTA / IP Paris transparent PNG (`Ensta-logotype-05-bleu-rvb.png`) from the [ENSTA RGB logo archive](https://www.ensta.fr/sites/default/files/content/article/pdf/LogoENSTA_RVB.zip), linked from [ENSTA's branding page](https://www.ensta.fr/logo-et-charte-graphique); cropped to 3,638 × 2,286 pixels |
+| `aid.png` | [Ministère des Armées / AID](https://www.defense.gouv.fr/sites/default/files/aid/logo.png), displayed on [AID's RAPID page](https://www.defense.gouv.fr/aid/deposez-votre-projet/rapid-regime-dappui-linnovation-duale) |
+| `ifremer.png` | Inline `logo-ifremer` SVG from [Ifremer](https://www.ifremer.fr/fr); rendered using the site's brand colour `#0032c6` |
+| `lip6.png` | Inline `LIP6` SVG from [LIP6](https://www.lip6.fr/); rendered using `--LIP6_logo_color: #25314F` from the site's `css/common.css` |
+| `sorbonne.png` | [Sorbonne Université SVG](https://www.sorbonne-universite.fr/sites/default/files/media/2019-10/logo_4.svg), rendered to PNG |
+| `academia-sinica.png` | [Academia Sinica](https://www.sinica.edu.tw/images/AS_logo_2.png), referenced by its [official website](https://www.sinica.edu.tw/en) |
+| `taipei.png` | [University of Taipei masthead](https://www.utaipei.edu.tw/var/file/0/1000/img/1583/366369593.jpg), linked from its [official website](https://www.utaipei.edu.tw/) |
+
+All nine files are tightly cropped RGBA PNGs with actual transparent pixels,
+not just an alpha channel containing an opaque white background. Existing alpha
+was preserved. For opaque sources, only white background connected to the outer
+edge was removed; white artwork inside the Academia Sinica seal was retained,
+and antialiased contour pixels were unmatted to avoid white fringes.
+
+The SVG-derived assets were rendered at high resolution (at least 1,900 pixels
+wide). UBO was re-rendered from vector paths, not upscaled from the old 489-pixel
+PNG; its SVG viewport was extended to preserve the descender in “Bretagne”.
+LIP6's white circular website backdrop was omitted, keeping the plain
+logotype; glyph paths, proportions and lettering were not changed. Compilation
+needs no SVG converter, network access or additional shell commands.
