Summary

Migrates IONOS-specific theming out of the two external submodules (`apps-custom/nc_theming`, `themes/nc-ionos-theme`) and into the core `apps/theming` app via a native `IonosTheme` class that implements Nextcloud's `ITheme` interface.

What changed

  • New `IonosTheme` class (`apps/theming/lib/Themes/IonosTheme.php`): implements `ITheme`, registered in `ThemesService` as `enforce_theme = ionos`. Provides IONOS color palette as CSS variables, custom CSS via `getCustomCss()`, Open Sans font-faces via `@font-face`, a `color-scheme: light dark` meta tag, and a dynamic `--current-year` variable (set from `date('Y')`) for the footer copyright string.
  • New test (`apps/theming/tests/Themes/IonosThemeTest.php`): 10 tests, 1 skipped (CSS `light-dark()` values not evaluatable by the hex checker). All other ThemesService tests pass (23/23).
  • IONOS CSS + assets migrated to `apps/theming/css/ionos/` and `apps/theming/img/` / `apps/theming/fonts/`.
  • Submodules removed from `.gitmodules` (`nc_theming`, `nc-ionos-theme`).
  • IONOS nc-config submodule bumped — see companion PR in nc-config (feat(theming): migrate from nc_theming to apps/theming IonosTheme nc-config#151): switches `enforce_theme = ionos`, updates favicon path, clears slogan (footer text now provided by CSS).
  • simplenavigation submodule bumped — see companion PR (fix(styles): resize header icons to 30px and tighten gap nc-simplenavigation#42): header icons resized to 30px, unified-search SVG max-size fix, icon gap 8px, IONOS logo on guest/share-link pages with full-width fixed header.
  • Layout fixes (browser-tested):
    • `body` background-color set for IONOS light/dark mode
    • `#content-vue` margin preserves `--header-height` offset
    • `--header-height` set to `64px` to match `simplenavigation`'s forced `height: 64px !important`
    • `--body-container-margin` set to `0px` to remove the 8px bottom gap
    • "Files settings" button hidden in sidebar (rule ported from `nc-ionos-theme/core/css/server.css`)
    • Breadcrumb button horizontal padding restored
    • `--color-primary-element` adapts to light/dark mode
  • CSS variable fix (`IonosTheme.php`): removed `--default-line-height: 24px` override. NC core uses this variable as a unitless multiplier in `calc()` expressions (e.g. `calc(var(--default-line-height) * 6 * var(--font-size-small))`). A `px` value produces `px²` which is invalid and silently collapses to `0px`. The default unitless `1.5` is visually equivalent (`1.5 × 15px = 22.5px`).
  • `public_share.css` (`apps/theming/css/ionos/public_share.css`): login page footer — removes box-shadow, centers full-width, replaces NC entity link text with `© YEAR IONOS SE` via CSS `::before` (year from `--current-year` variable; href still points to `ionos_homepage` from system config). Footer is hidden entirely on `body#body-public` (public share pages). Also contains `.guest-box` card styling for password-protected shares and file drop forms.
  • `files_sharing.css` reworked: removed ~560 lines of dead code referencing PHP-era selectors that no longer exist in V33 (`#header-primary-action`, `.files-filestable`, `#ionos-global-nav`, `#notemenu`, `#downloadFile.button`, etc. — all replaced by Vue-based rendering since NC 25). The file now only contains sharing sidebar styles (`#app-sidebar-vue .sharingTab`, `li.vs__dropdown-option`).
  • `buttons.css` fix: `#body-login a.button:hover` referenced undefined `--ion-button-tertiary-text-hover`; corrected to the existing `--ion-button-tertiary-text`.

Dependencies

Test plan

  • Run `phpunit apps/theming/tests/Themes/IonosThemeTest.php` — 10 tests pass, 1 skipped
  • Run `phpunit apps/theming/tests/Service/ThemesServiceTest.php` — 23/23 pass
  • Set `enforce_theme = ionos` in `config/config.php`, clear cache, verify IONOS theme loads
  • Verify `#content-vue` is not overlapping the header
  • Verify no 8px gap at the bottom of the viewport
  • Verify "Files settings" button is not visible in the sidebar settings section
  • Verify Open Sans font loads correctly
  • Verify body background is white in light mode, `#02102B` in dark mode
  • Verify header icons (search, mail, account) render at 30px
  • Verify breadcrumb "Alle Dateien" button has horizontal padding
  • Verify IONOS logo appears on password-protected share link pages (not the default NC logo)
  • Verify guest header spans full viewport width on share-link/login pages
  • Verify login page footer shows `© YEAR IONOS SE` centered, no shadow or background; year matches current year
  • Verify public share pages (`body#body-public`) show no footer
  • Verify password-protected share form box has IONOS card styling (rounded corners, correct background)
  • Verify two-factor provider selection page (`/login/selectchallenge`) — button hover/focus styles render correctly
  • Verify `AbsenceForm` and similar components using `calc(var(--default-line-height) * ...)` render at non-zero height
  • Confirm `nc_theming` and `nc-ionos-theme` submodules are no longer referenced

IONOS(theming): restore header margin on #content-vue in _layout.css
af0ab15 
margin: 0 was removing the top margin that positions content below the
NC header. nc-ionos-theme's server.css previously compensated with
margin-top: 64px !important. Replace with margin-top: var(--header-height)
which is correct now that the OC_Theme is gone.

IONOS(theming): set --header-height 64px and --body-container-margin 0px
cf5760c 
simplenavigation forces #header to 64px via !important, so --header-height
must match for margin-top: var(--header-height) on #content-vue to be correct.
--body-container-margin defaults to 8px in NC (2 * grid-baseline) which left
a gap at the bottom; IONOS uses a flush full-height layout so 0px is correct.

IONOS(theming): fix invalid --default-line-height px override
154c3c8 
Removed and fallback to default --default-line-height: 1.5; from css/default.css

NC designed --default-line-height as a unitless ratio (like CSS
line-height: 1.5), not a length. It is used in expressions such as:

  calc(var(--default-line-height) * 6 * var(--font-size-small))

With 24px this becomes px * px (invalid unit), which the browser
discards — the property silently collapses to 0px. With the unitless
default 1.5 it becomes number * number * px = px, which is valid.

Setting a px value works where the variable is used directly as a
line-height property (lengths are accepted there), but breaks every
calc() multiplication. Removing the override lets DefaultTheme's 1.5
apply, which is visually equivalent (1.5 * 15px = 22.5px).

IONOS(theming): rework files_sharing.css for V33 public share page
922eb7b 
Remove ~560 lines targeting selectors that no longer exist in V33
(PHP-rendered public share UI was replaced by Vue in NC 25+):

- @media rules for #header-primary-action / #header-actions-menu
  (replaced by #public-page-menu--primary / #public-page-menu)
- #content.app-files_sharing subtree: .files-filestable, .files-controls,
  #view-toggle, #uploadprogressbar, .newFileMenu, .breadcrumb .crumbhome,
  #imgframe, #downloadFile.button, .popovermenu — all PHP-rendered, gone
- #notemenu — never existed in V33
- #ionos-global-nav — from old OC_Theme custom header template, gone
- .header-info :not(:has(+#content .directDownload)): .directDownload
  never exists in V33, permanently hiding .header-info (bug)

Keep V33-alive selectors:
- #app-sidebar-vue .sharingTab / .sharingTabDetailsView__quick-permissions
- .guest-box card (password-protected share / file drop form)
- li.vs__dropdown-option (SharingInput.vue uses Vue Select)

Hide footer on public share pages (body#body-public footer.guest-box):
layout.public.php renders a footer that is not part of the IONOS
public share design.

which renders under RENDER_AS_GUEST (body#body-login) and contains
<a class="button primary two-factor-primary"> elements.
