marketing/facebook: the mark alone on the profile, the real lettering on the covers
Operator refinements after looking at the rebuilt pictures. No geometry changed:
R-919's measured constants, its band and every check stand, and the red-proof
still convicts the old layout.

Profile picture: the logo MARK only. The mark plus the "felhom.eu" lettering was
too much for the 176 px Facebook shows -- and smaller than the shape the Page
carried before this work, because build.py shrinks the artwork to fit inside the
circle where the original was simply cropped by it. Dropping the lettering grows
the mark from 69% to 76% of the circle; canvas 932 -> 648 and the profile_width
floor 720 -> 640 (twice Meta's recommended 320 source; 720 was above what the
mark alone needs and would have shrunk it for nothing). logo.png is split at a
MEASURED row: ink y 5-289, blank band y 290-295, wordmark y 296-403.

Covers: the headline is now set the way the WEBSITE sets its h1. site.css
.page-index .hero-text h1 is font-weight 700, letter-spacing -0.03em; this file
used ExtraBold 800 with no tracking, so the cover did not actually match the
page. HEADLINE_WEIGHT/HEADLINE_TRACK now carry those, with real per-glyph
spacing. Bold is narrower so headlines grew: A 57->62, B 58->63, C 47->50.

"felhom.eu" is no longer typed anywhere: wordmark() draws the logo's own
lettering, which is set in "M+ 2c"/"Vremena Grotesk" -- fonts this machine does
not have (R-916) -- so any typed version was a look-alike. The website hero
shows the same logo.png on the same dark background, so the covers match the
page. The DOMAIN constant is removed rather than left as dead code.

Caught before it shipped: the preview's new profile paragraph added a fourth %d
and the argument tuple stayed in the old order, so the phone paragraph rendered
"the centre 76 px of the 938-pixel width, with a profile circle 1640
cover-pixels across". Every number was real, just in the wrong slot, which is
why it read as plausible instead of crashing. Found by reading the rendered
paragraph back, not by the exit code.

Built on DooPlex; all checks pass, the phone simulation still shows 0 px cut and
0 px under the profile circle on all three covers. R-919 stays VERIFY.

Raw Blame History

marketing/facebook — the Felhom.eu Facebook Page's pictures and texts

Files the operator uploads and pastes by hand. Nothing here talks to Facebook (the robot posting path is R-914).

Rebuild

python3 marketing/facebook/build.py

One command makes every PNG and out/preview.html, and runs the checks: the profile circle (no logo pixel outside 0.42 x width; shown failing first on today's shape), the cover safe area (content inside what computer AND phone show, clear of both profile circles), the headline's capital height, and the sizes read back from the files. Exit 0 = all passed. Needs Python 3 + Pillow only.

Build it on DooPlex. The PNGs are byte-reproducible there (Pillow 11.1.0 — a rebuild leaves git status clean) and NOT across Pillow versions: Pillow 12.3.0 on the Windows workstation re-renders the same text a pixel or two differently and rewrites all six files. Measured 2026-10-09. Brand source: website/assets/logo.png (the logo master — see below), website/assets/site.css tokens, website/assets/fonts/ (Plus Jakarta Sans).

Facebook's current Pages experience has no long-description field: not in the Page's „Névjegy" tab, not in Business Suite's „Oldal módosítása", not in Page settings; the Graph description reads null and writing it needs pages_manage_metadata, which the robot key does not have.

Sizes used (READ, Meta's help page — and it does NOT confirm most of ours)

Meta's own help page (facebook.com/help/125379114252045) was read first-hand on 2026-10-08 from the Windows workstation, quoted verbatim in documentation/audits/facebook-page-setup-2026-10-08/A-meta-sizes.md. It does not carry most of the figures this section used to assert. What it does say: cover 16:9 on a computer and 2,4:1 on a phone, minimum 400 x 150 either way, fastest-loading file sRGB JPG 851 x 315 under 100 kB; profile picture shown 176 x 176 on a computer, 196 x 196 on a smartphone, 36 x 36 on a feature phone, best source 320 x 320, cropped to a circle; the profile circle overlaps the cover by about 40 px on mobile; and PNG beats JPG when the picture carries a logo or text. Meta's page contradicts itself — it gives two ratios and then recommends one 2,70:1 file for both — so the figures below are kept as ours, not as Meta's.

The second-hand figures this section used to carry (cover shown 820 x 312 on computers, 640 x 360 on phones, profile circle over the cover at 16 px / 176 px and 24 px / 196 px; sources postfa.st, linearity.io, fasturtle.com) appear nowhere on Meta's page; only the 176 px profile size matched. The mobile overlap we assumed, 24 px, is smaller than the ~40 px Meta states.

What we build: the cover at 2 x, 1640 x 624, well above both stated minimums, as PNG; the profile picture 648 x 648, twice Meta's 320 x 320 recommendation and therefore downscaled, not enlarged.

MEASURED on the live Page 2026-10-08, both widths:

  • Computer (1435 px viewport): fine. The cover renders whole — no crop, no distortion — the cover container caps at 1250 px, and the profile circle sits 16 px below the cover, so it covers no cover text.
  • Phone (emulated Pixel 9, 412 x 924): the cover WAS cut — R-919, fixed 2026-10-09. The mobile Page header is 412 x 274 = 1,504:1, so Facebook keeps the full height and shows only the centre 938 px of the 1640 px width (57,2 %) — 351 px cut from each side. The old safe area was the centre 1028 x 544, i.e. 306 px clear of each edge: 45 px per side too wide. The light text of the old cover-c.png ran from x 333 against a left crop edge of x 351, so 18 px of it were cut — the headline read „aját szabályaid" and the wordmark „elhom.eu" on every phone. The mobile profile circle is 172 px and centred, hiding source x 637–1030 x y 369–624.

What the build does about it now (2026-10-09)

build.py takes the phone view from the measurement, not from Meta: PHONE_HDR = (412, 274) gives CW_PHONE = 938 px, so SAFE is the centre (391, 40)–(1249, 584) — 858 px wide, MARGIN 40 px inside each crop edge. The phone profile circle is the measured centred box (637, 369, 393), and QUIET is no longer one formula for both circles: the computer one is left-anchored (everything to its left is under it), the phone one hides only its own box. Every cover is drawn inside BAND — inside SAFE, right of the computer circle, above the phone circle — which is derived from those constants, so a re-measurement moves the designs with it. A cap check keeps each headline's capital at ≥ 4 % of the cover height (25 px), so the text survives the phone shrinking the cover to 412 px.

The check was shown failing first. Against the covers as committed at a76207945e: cover A was 23 px over on the left and 22 px on the right, cover B 63 px / 58 px with 1017 content pixels under the phone circle, and cover C 63 px / 82 px with 1778 under it — 3 of 3 convicted.

Grade of the phone figures: MEASURED, but on ONE device (Pixel 9 emulated, 412 px, the mobile website). Not measured in the Facebook app and not at any other width — which is why MARGIN is 40 px and why the operator's check in the app is the acceptance step. Meta's stated mobile ratio of 2,4:1 is not what the Page header does (1,504:1 measured), which is why a figure from Meta's page is no substitute for looking at the Page. Getting Facebook's phone layout at all needs DevTools device mode plus a reload; the audit's README has the recipe.

Page about = 100 characters: developers.facebook.com/docs/graph-api/reference/page/ (Meta, first-hand). The Page's own „Bemutatkozás" editor counts to 255 (seen on screen 2026-10-08); §1 is 99 characters, so neither limit bites.

The logo master

website/assets/logo.svg is not usable as a master: its „felhom.eu" lettering is live text in the fonts „M+ 2c" and „Vremena Grotesk", which DooPlex does not have, so any renderer here draws other letters. The PNG (645 x 408) is placed unscaled. A vector master with the lettering converted to paths (Inkscape: Path → Object to Path, on the machine that has the fonts) is R-916.

Cover C

Uses website/assets/dashboard-backups-hu.webp (demo box, already public on the website). The demo box's domain chip next to the title is covered with the page colour in the copy; the source file is unchanged. No third-party logo appears in it (app names are text). The Launcher and Apps pictures were not used: they show app logos.
