/* =====================================================================================================
   فرحتي — invitation page structure (shared by every theme and opening).
   Load order: /invite.css  →  /t/<theme>.css  →  /o/<opening>.css  →  /invite.js

   THEME CONTRACT — a theme is ONE file public/t/<id>.css (+ one entry in designs.json). It must not need any
   markup change. Scope every rule under html.t-<id> (the <html> element carries t-<id>, o-<opening>, occ-<type>).
   Fonts: @import Google Fonts at the very top of the theme file.

   1) Custom properties a theme may set (defaults below in :root):
      palette   --bg --paper --ink --muted --accent --accent-hi --accent-lo --on-accent --line --field --ok --no
      type      --display --body --ui --fs (body size, keep ≥17px) --body-w (body weight) --lh --names-fs --names-lh --names-w --h2-fs --h2-w
      shape     --radius --btn-radius --cover-radius (single length, or a full border-radius list — then ALSO set
                --cover-frame-radius, used by the frame + album tiles) --shadow --map-filter (filter on the map iframe)
      artwork   (SVG data-URIs used as CSS MASKS, painted in --accent — draw in any opaque colour, alpha = shape)
                --orn-hero   crown ornament above the names (.hero-orn), size --hero-orn-w / --hero-orn-h
                --orn-div    divider between sections (also the small rule on opening cards)
                --orn-corner top-left corner piece; mirrored automatically into 4 hero corners, size --corner-size
                --orn-bullet bullet of the notes list
                --texture    background-image layers for the page (<html>) and the opening overlay
                Defaults are an EMPTY svg (invisible). Never set an ornament to `none` — mask:none paints a solid box.
      openings  --op-bg (overlay background colour)
                envelope: --env --env-2 --env-edge --env-ink --seal --seal-hi --seal-lo --seal-ink
                doors:    --door-img  (9:16 photo of closed double doors, seam at the centre: /o/img/doors-ivory|walnut|emerald|navy|blush.jpg)
                scratch:  --foil-img  (foil texture: /o/img/foil-gold|rose|silver.jpg) --foil-1 --foil-2 --foil-3 (fallback gradient) --foil-ink

   2) Decorative hooks a theme may style (all exist on every page; free pseudo-elements are marked ✓):
      body::before ✓ body::after ✓         fixed full-viewport backdrop layers (stars, vignette…) — keep z-index:-1
      .sheet ::before ✓ ::after ✓          the content column — page frame (double lines, borders…)
      .hero ::before ✓ ::after ✓           hero backdrop (arch, halo, moon…)
      .hero-orn / .hero-orn.bottom          crown ornaments above and below the hero text
      .corner.c1 .c2 .c3 .c4                hero corner pieces (top-left, top-right, bottom-left, bottom-right)
      .sec + .sec::before                   section divider (already painted from --orn-div; restyle size/opacity)
      .sec h2 ::after ✓                     heading flourish
      .cover-frame ::before ✓ ::after ✓     frame around the cover photo
      .names .n / .amp / .line / .hosts / .hosts.sign / .hero-date .hd-day / .hd-side
      .cd-cell .wish .rsvp-state .choice span .map .shot .btn-solid .btn-line   surfaces
      .op-plaque .op-card .env-card ::before ✓ ::after ✓   opening cards

     hero.jpg  9:16 photo of a blank card/paper in the same material world (names are typeset on it live)
     thumb.jpg small preview for the galleries
   The theme file sets: --art-open, --art-hero (urls), --art-pad (padding that keeps the hero text inside the blank
   paper area of hero.jpg: top sides bottom — CSS padding % is relative to the hero WIDTH, so a vertical inset of N% of the image height is written as N×1.78%), --art-veil (wash over the blurred backdrop), palette + fonts.
